IGNOU Bio assignments are carefully designed to cover both theoretical and practical aspects of the course. For undergraduate programs, assignments may include questions on cell biology, genetics, ecology, animal and plant physiology, and microbiology, often requiring diagrams, illustrations, or experimental observations. Postgraduate assignments, such as those for M.Sc Zoology, focus on advanced topics like molecular biology, taxonomy, wildlife biology, biochemistry, and research methodology, allowing students to develop critical thinking and research skills.
