MP Board Class 11th Biology Notes Chapter 1 The Living World

→ Hippocrates and Aristotle tried for the first time to classify the organisms systematically.

→ Theophrastus is known as ‘father of botany’.

→ Carolus Linnaeus is called as ‘father of taxonomy’.

→ Viruses are the border line of living and non-living things.

→ John Ray was first to describe the natural system of classification.

→ Euglena can live double lives. In presence of light and absence of organic matter it become green photosynthetic like plants, but in presence of organic matter or in the absence of light energy they absorb or ingest food like the protozoans. Due to this ability they were earlier included in the plant kingdom by botanists and in the animal kingdom by zoologists.

→ Protists known as ‘slime moulds’ are devoid of a cell wall in the vegetative phase and ingest particular matter. But in the reproductive phase they develop a cell wall as in some fungi.

→ The evolutionary history of any group of organisms is called phylogeny.

→ Viruses are the connecting link of living and non-living things.

→ At present more than 1-7 million species of organisms have been identified and named.

→ The basic unit of classification is species.

→ Viruses are made up of protein and nucleic acid, RNA or DNA.

→ Arranging living organisms in different groups based on their morphology is called as classification.

→ Smallest group of a classification is called as Species and Largest category is called as Kingdom.

→ Scientific name of living organisms consists of two words. First word is called as Generic name and second word is called as Specific name.

→ Scientific name of man is Homo sapiens.

→ Linnaeus was the first to establish and define hierarchy of taxonomic categories.

→ Full form of ICBN is “International Code of Botanical Nomenclature.”

→ Full form of ICZN is “International Code of Zoological Nomenclature.”

→ Taxon : The Taxa are the groups of organisms, generally group of species.

→ Species : Species is a population of interbreeding individuals.

The Living World Class 11 Important Questions Short Answer Type

Question 1.
Why classification of living organisms is needed?
Answer:
In nature approximately 22,50,000 species are found. It is not possible for man to study all the plants and animals during his lifetime. Therefore, classification of all these organisms is necessary to make their study easy. In addition to it, classification also makes following easy:

• It helps to understand diversity in plants and animals.
• It helps us to establish the natural relationship among organisms.
• It helps us to identify the organism.
• It helps us to understand about origin of the organisms and their relationship.
• It gives us evidence for organic evolution, thus helps us to understand organic evolution.

Question 2.
Give Scientific names of following organisms :
1. Onion,
2. Man,
3. Elephant,
4. Tapeworm,
5. Frog,
6. Wheat,
7. Rice,
8. Mustard,
9. Pea,
10. Mango.
Answer:
Common name – Scientific name

1. Onion – Alium sepa
2. Man – Homo sapiens
3. Elephant – Elephas indicus
4. Tapeworm – Taenia solium
5. Frog – Rana tigrina
6. Wheat – Triticum aestivum
7. Rice – Oryza sativa
8. Mustard – Brassica compestris
9. Pea – Pisurn sativum
10. Mango – Mangifera indica.

Question 3.
Why classification changes time to time?
Answer:
Classification changes time to time due to evolution. Evolution causes formation of new species, which are then added to the old classification.

Question 4.
On the basis of which of the following you will like to classify the people you meet:
Dress, Mother tongue, State where they live, Economic standard etc.
Answer:
First of all we classify the people we meet on the basis of their mother tongue, then the state where they live, at the end their dress, religion, species and physical appearance is considered.

Question 5.
What Knowledge we gain by identification of Individual and Population?
(NCERT)
Answer:
By identification of individual and population we can understand about inter-relationship between all organisms. It helps to understand about similarity and dis-similarity between living organisms.
e.g., There are two different species of potato :
Genus – Species
Solarium – tuberosum
Solanum – nigrum.

Question 6.
Define Taxon. Give some examples of taxa in hierarchical classification.
Answer:
Taxon is a group of living organisms. Each taxa is placed at some level of hierarchy.
e.g., Insect represent a class of phylum Arthropoda. Presence of three pairs of jointed legs is the similar characteristic of insects.
Example of Taxa are various categories such as kingdom, phylum, class, order, family, genus and species, which altogether forms hierarchic classification.
Modern Taxa or Classification of Man :
Kingdom – Animalia
Phylum – Chordata
Class – Mammalia
Order – Primates
Family – Hominidae
Genus – Homo
Species – sapiens.

Question 7.
Write the basic characters of five kingdom classification.
Answer:
Five kingdom classification is proposed on the basis of:

1. Complexity of cell structure : Prokaryotes and eukaryotes.
2. Complexity of the body of the organism: Unicellular and multicellular.
3. Mode of nutrition : Autotrophs and heterotrophs.
4. Life style.
5. Phylogenetic relationship.

Question 8.
What do you understand by binomial nomenclature? Also write the scientific name of any two organisms on the basis of binomial nomenclature.
Answer:
Binomial nomenclature :
Nomenclature is the naming of plants or animals. Binomial nomenclature system is a system of naming plants and animals which was introduced by Carolus Linnaeus. According to this system every organism is given two names a generic name followed by a specific name or epithet. The generic name (i.e., name of genus) is a noun and the specific epithet is an adjective indicating which of the several members of the genus has been considered. Both the names are written in italics.

The generic name is always capitalized while specific name is written in small letters, e.g., the zoological name of frog on the basis of this system is Rana tigrina. Here Rana indicates generic name while tigrina indicates its specific name. Binomials when written should always be underlined and when printed they must be italicized.

Scientific name of two organisms :
General name – Scientific name

1. Frog – Rana tigrina
2. Man – Homo sapiens.

Question 9.
Explain phylogenic line.
Answer:
Phylogenic line :
The evolutionary history of an organism is called phylogeny and various species of phylogeny are called phylogenic line. Phylogenic line indicates the sequence of evolution of a species.

The body of well developed organism is formed from a single cell, various changes occur in the cell and finally it is developed into an organism. The first unicellular organism is evolved on the earth like that of above process, then various changes occurred according to environment thus, various species evolved. In this phylogenic line organisms of kingdom monera appeared for the first time, from which protists have evolved. The kingdom plantae, animalia and fungi evolved from kingdom protista in various lines.

Question 10.
Explain the utility of five kingdoms classification.
Answer:
Significance or utility of five kingdoms classification :

• Prokaryotic organisms are placed under separate kingdom in this classification.
• Unicellular and multicellular organisms are grouped separately.
• Fungi are placed in separate kingdom due to variation in their mode of nutrition.
• Photosynthetic and non-photosynthetic organisms are grouped separately.
• This classification is more natural than binomial classification.
• The basis of this classification is bio-organization and mode of nutrition, hence it shows the sequence of evolution.

Question 11.
Write the name at least two examples of five kingdoms of organism.
Answer:
Five kingdoms as proposed by Whittaker are as follows :

1. Kingdom Monera : e.g., (i) Rhizobium, (ii) Nostoc.
2. Kingdom Protista : e.g., (i) Amoeba, (ii) Euglena.
3. Kingdom Plantae : e.g., (i) Brassica compestris (Mustard), (ii) Mangifera indica (Mango).
4. Kingdom Fungi: e.g., (i) Rhizopus, (ii) Agaricus.
5. Kingdom Animalia : e.g., (i) Homo sapiens (Man), (ii) Ratus ratus (Rat).

Question 12.
Write down the utility of systematics.
Answer:
Utility of Systematics :

• Systematics provide us with a means to study a group of organisms and get a fair idea about the essential features of organisms belonging to that group.
• Systematics provide a tool to identify fossils and newly discovered organisms.
• Systematics is complementary to all branches of basic and applied biology. It is required for the identification of any organism of interest to us whether it be economically useful, harmful, dangerous, disease producing, a pest or a parasite.
• Systematics provide basic information required in many disciplines of agricultural, medical and veterinary science.
• Systematics allow us to know about diversity, relationships and evolutionary tendencies amongst organisms.

Question 13.
What is two kingdom classification? Write its utility.
Answer:
Carolus Linnaeus classified all the living organisms into two main kingdoms :

1. Plantae (including all plants),
2. Animalia (including all animals).

Utility of two kingdom classification are :

• It has put together the unicellular with multicellular organisms.
• It has put together eukcaryotes (organisms with true nucleus in their cells), with procaryotes (organisms without true nucleus).
• It has put together autotrophs and heterotrophs, such as non-photosynthesizing fungi with photosynthetic green plants.
• It has little regard for diversified form.
• Lichens is a peculiar group of dual organisms which are formed by an association between an algae and fungus. They have neither plant character, nor any animal character.
• Group of unicellular algae (e.g., euglenoids, diatoms and dianoflagellates) and Protozoa show sufficient degree of resemblance.

Question 14.
Differentiate between :
(a) Monera and Protista,
(b) Autotroph and Heterotrophs,
(c) Plantae and Fungi.

(iii) Classification : It is defined as a system of arrangement of organisms into groups showing relationships.
(iv) Identification : It refers to the determination of correct position by an organism in the plan of classification.
(v) Nomenclature: It is the process of giving scientific names to the plants and animals.

Question 16.
What do you understand by trinomial nomenclature?
Answer:
Trinomial nomenclature :
Sometimes organisms of same species differs from each other as they are adapted for different kinds of environment. In such cases species are again divided into subspecies. The scientific name of such organisms consists of three words. The first word indicates generic name and begins with first letter as capital. The second word is species name and begins with first letter as small and the third word is the subspecies name which also begins with first letter as small. The system of naming the organisms using three words is called as Trinomial nomenclature. For e.g., the species of crow of different places are named as follow :

• Indian crow – Corvus splendens splendens
• Burmese crow – Corvus splendens insolens
• Crow of Sri Lanka – Corvus splendens protagalus.

The Living World Class 11 Important Questions Long Answer Type

Question 1.
What is Hierarchial System of classification? Explain it briefly.
Answer:
The term ‘Hierarch’ means a series of succession of different ranks. In biological classification, hierarchy is a system of arrangement where taxonomic categories are placed in order of logical sequence. There are seven hierarchies of categories or group in ranks which are placed one upon another and any species can be traced to these seven basic categories.

Kingdom is the highest taxonomic category, species is the lowest category of hierarchy that is grouped into genus based on common characteristics. The similar genus are grouped into a family and the similar families into an order, similar orders into a class and similar classes into a phylum. The similar phyla are grouped into kingdom.

Question 2.
Write down the outline of Five Kingdom Classification giving two examples of each? Also give the advantages of it.
Or
Write the name and one important basic features of five kingdom which proposed by Whittaker.
Answer:
Five Kingdom classification : It is divided into five groups, they are :

1. Kingdom Monera : It includes prokaryotic and unicellular organisms e.g., (a) Rhizobium, (b) Nostoc.
2. Kingdom Protista : It includes eukaryotic and unicellular organisms e.g., (a) Amoeba, (b) Euglena.
3. Kingdom Plantae: It includes multicellular organisms with photosynthetic pigments in plastids are present, e.g., (a) Pitcher plant, (b) Sundew plant.
4. Kingdom Fungi: It includes eukaryotic, multicellular organisms with heterotrophic mode of nutrition, e.g., (a) Agaricus, (b) Mucor.
5. Kingdom Animalia: It includes multicellular, heterotrophic made up to Eukaryotic cell, e.g., (a) Rana tigrina (Frog), (b) Panthera leo (Lion).

Question 3.
Give basis and demerits of five kingdom classification.
Answer:
Five kingdom classification is proposed on the basis of:

1. Complexity of cell structure : Prokaryotes and eukaryotes.
2. Complexity of the body of the organism : Unicellular and multicellular.
3. Mode of nutrition : Autotrophs and heterotrophs.
4. Life style.
5. Phylogenetic relationship.

Demerits or disadvantages of five kingdom classification :
There are many advantages of five kingdom classification therefore it is very popular and accepted by all scientists but still there are some shortcomings.

1. Unicellular algae are kept in kingdom protista whereas algae like multicellular organisms are kept in kingdom plantae. But similar organisms must be put together.
2. There is diversity in kingdom protista. Dissimilar organisms must not be kept in same group.
3. All organisms other than Moneron show that they are polyphyletic in origin. It is a great shortcoming of this classification.
4. There is no place for viruses in this classification.
5. Similar organisms are kept far from each other. For example unicellular and multicellular algae.

Question 4.
Collect all modern meaning of word ‘Species’. Can you discuss with your teacher to know about species of higher category of plants, animals and bacteria ?
(NCERT)
Answer:
The ‘Species’ was used for the first time by John Ray. According to him, Species is a population of individual having common gene pool. According to Mayer (1942), Species is group of inbreeding population. According to modem concept, the group of individuals having the following characteristic features is called a species:

• All the members inbreed freely.
• All the individuals of a population have common gene pool.
• Adaptation and natural selection is continued in the group according to environment.
• All the members of this group possess the capacity to produce new species by organic evolution.

Examples of Species of higher category plants are :
Mangifera indica (Mango), Solarium tuberosum (Potato) and example of higher category animals are : Panthera leo (Lion), Panthera tigris (Tiger), Eliphas indicus (Elephant). First word of all above examples are Generic name whereas second word of all above scientific names are species name. Such as indica for mango, tigris for tiger.

Whereas bacteria are classified into different groups on the basis of their shapes such as : Coccus (Spherical), Bacillus (Rod shaped), Vibrio (Comma shaped), Spirillum (Spiral shaped).

Question 5.
How key is useful to identify and classify living organisms?
Answer:
Following classification and nomenclature a taxonomist constructs a key to make it possible for other biologists to identify the species. A Key is a device by which each type in a group of organisms can be identified. A key provides convenient way for easy identification of an organism by applying diagnostic characters. There are two types of keys: (i) Biforked key, (ii) Bracketed key. An example of a key to identify a fish, frog, snake, bird, bat and cat is given below:

• Does the organism have external pinna : Yes (go to 2); No (go to 3)
• Does it fly : Yes (Bat); No (Cat)
• Does it fly : Yes (Bird); No (go to 4)
• Does it have limbs : Yes (Frog); No (go to 5)
• Does it have gills : Yes (Fish); No (Snake).

Question 6.
Explain following terms and define them :
(i) Phylum,
(ii) Class,
(iii) Family,
(iv) Order,
(v) Genus.
Answer:
(i) Phylum :
A group of one or more classes having certain common diagnostic characters but differ from other classes of other phyla in some diagnostic characters is called as Phylum.
e.g., Phylum Chordata includes classes pisces, amphibia, reptilia, aves and mammalia.

(ii) Class :
It consists of one or more orders having certain common characters which differs from order of other classes in some characters is called as class.
e.g., Class Mammalia includes orders primates (gorilla, man), carnivora (dogs, cats, lions) etc.

(iii) Family :
It is the taxonomic category containing one or more related genera having certain common characters, which is separated from other related families having certain different characters.
e.g., Family Felidae includes lion, leopard, tiger etc.

(iv) Order :
It consists of one or more families having certain common characters which differ from families of other orders in some diagnostic characters.
e.g., the order carnivora includes the Families Felidae (lion, leopard, tiger) and Family Canidae (dogs, foxes).

(v) Genus:
It is the second category of classification. Genus is group of similar species.
e.g., Genus Panthera includes Lion, Leopard and Tiger etc.

Question 7.
Explain taxonomic hierarchy by giving examples of plants and animals.
Answer:
In classification plants and animals are placed in various smaller and large groups. These groups are called as taxon and category. Hierarchy is a system of arrangement for classification in which taxonomic categories are placed in a subsequent way on the basis of characteristics and evolution of the organisms.

The hierarchy of categories consists of a descending sequence of seven categories, which are Kingdom, Phylum, Class, Order, Family, Genus and Species.

Lowest taxonomic category is species and the highest taxonomic category is Kingdom. Ascending sequence of these categories are :
Organisms of lowest categcxy species shows similarity but as we go to higher level towards kingdom similar characters decrease and dis-similarities increase.
