Zoology For B.Sc. Students Semester IV: MJC 5, 6 & 7 | Cell Biology | Endocrinology | Ecology - NEP 2020 Bihar

This textbook has been designed to meet the needs of B.Sc. Fourth Semester students of Zoology for Patna University and other Universities in Bihar under the recommended National Education Policy 2020. It comprehensively covers the theoretical and practical aspect of the papers, namely, 'MJC 5: Cell Biology', 'MJC 6: Endocrinology' and 'MJC 7: Ecology'.

The theoretical sections of the textbook cover essential topics across Cell Biology, Endocrinology, and Ecology, providing a comprehensive foundation for students.

In Cell Biology, the theory explores the fundamental principles of cellular structure and the functions of organelles involved in a range of cellular processes. Topics include cell growth, division, survival, death, and the regulation of these critical processes. Additionally, the theory discusses cell signaling and its role in maintaining cellular functions, as well as how defects in organelle function and the regulation of cellular processes can lead to disease development.

The Endocrinology section focuses on the endocrine system, outlining the basic properties of hormones and their importance. It emphasizes the endocrine system's collaborative role with the nervous system in maintaining homeostasis and how hormonal regulation impacts physiological processes and disease development.

The Ecology section delves into population characteristics, dynamics, growth models, and interactions, as well as community structures, ecosystem development, and climax theories. It covers various types of ecosystems, food chains and webs, energy flow, and ecological efficiencies. The textbook also highlights the application of ecological principles to wildlife conservation and management.
