UP Board Class 11 Biology – Animal Kingdom
The chapter “Animal Kingdom” in UP Board Class 11 Biology introduces students to the diverse world of animals and explains how they are classified based on body structure, symmetry, germ layers, coelom, segmentation, and patterns of reproduction. This chapter follows the modern classification system, dividing the animal world into important phyla such as Porifera, Coelenterata (Cnidaria), Platyhelminthes, Nematoda, Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata, and Chordata.
Students learn about key features like the presence of notochord, types of body cavities (acoelomate, pseudocoelomate, coelomate), body symmetry, and levels of organization. The chapter also explains the differences between vertebrates and invertebrates, highlighting unique characteristics of fish, amphibians, reptiles, birds, and mammals.
By studying “Animal Kingdom,” learners gain a deep understanding of evolutionary trends, structural adaptations, and ecological roles of animals. This chapter builds a strong base for higher studies in zoology and proves highly valuable for competitive exams like UP BOARD NEET, CUET, and other medical entrance tests.
