Microbiology & Immunology

Download Q&A

Microbiology & Immunology focuses on the study of microorganisms and the immune system, explaining how microbes interact with living organisms and how the body defends itself against infections. This category is designed for Class 11–12 students, NEET aspirants, and undergraduate learners to build strong conceptual and applied understanding.

In this section, you will study:

  • Classification and characteristics of microorganisms

  • Structure and life cycles of bacteria, viruses, fungi, and protozoa

  • Beneficial and harmful roles of microorganisms

  • Principles of innate and acquired immunity

  • Cells and organs of the immune system

  • Antigens, antibodies, and immune responses

  • Vaccination and immunological memory

  • Basics of immune disorders and hypersensitivity

  • NCERT-based explanations, diagrams, MCQs, and exam-oriented questions

The content is structured to develop conceptual clarity, enhance diagram and mechanism-based understanding, and help students perform confidently in school examinations, NEET, and undergraduate assessments.

Build a strong foundation in microbiology and immunology to understand disease, immunity, and the biological basis of health and protection.
