After in-depth learning of the plant kingdom, comes the turn of the animal kingdom to explain itself to the students. Since birth, we all have been seeing different animals, in different forms, living in different structures and conditions. To date, more than a million animal species have been found and described that has made classification even more essential to understand the nature and type of the animals.
Therefore, to thoroughly teach the students about the animal kingdom, this chapter has been included in the NCERT Solutions for Class 11 Biology where the Basis of Classification, How Classification of Animals is done, and other relevant topics have been discussed. This classification is also required to correctly assign a systematic position to the freshly discovered species of animals. These are the topics described in this chapter:
A few fundamental attributes about cell organization, nature coelom, body symmetry, circulatory pattern, digestion pattern, or the pattern of the reproductive system are commonly found in various living organisms. These common fundamental attributes serve as the basis upon which animals are classified, and these attributes have been elaborated in this section.
The Kingdom Animalia's basic classification is done based on Diploblastic and Triploblastic Organization, Symmetry, Segmentation, Notochord, and Coelom. These topics will impart core knowledge about various categories of animals.
