___________
1. Ans : Natural classification recognises three types of views, such as:
(i) Phenetic classification
ii) Cladistic classification and
(iii) Evolutionary classification.
____________
2. Ans : Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia. The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition andreproduction, and phylogeneticrelationships.
____________
3.Ans : So we can say, all vertebrates are chordates as they have notochord but all chordates are not vertebrates because other sub phyla of chordateslike cephalochordates -have notochord from head to tail region throughout their
life.
___________
4. Ans : The grade of organisation tells us about the Oraganism composition which is higher cell, tissue,organ And on the basis of composition grade is decided.

Symmetry is the dividation of Oraganism.
It is of 3 Types
1. Asymmetry
Organism cannot be divided into two halves from any plane. Eg Amoeba
2. Bilateral
Organism can be divided into two halves by cutting from a particular plane. Eg Human
3. Radial
Organism can be divided into two halves from any plane. Eg. Starfish
____________
5. Ans: Benefits of usingclassification schemes. Using one or moreclassification schemes for the classification of a collection of objects has many benefits. Some of these include: It allows a user to find an individual object quickly on the basis of its kind or group.
OR
The scientific grouping of organisms has some specific advantages.
It makes the study of living organisms convenient.
It helps in the specific identification of any given organism.
The study of a few representatives from each distinct group helps us to integrate the idea of life as a whole.
It reveals the relationships among various groups of organisms.
It provides information about plants and animals, which occur in specific geographical regions.
It indicates the evolutionary relationship by establishing the gradually increasing complexity of form and structure in different groups of organisms.
