Practical Biology For Class XI By Dr. R. C . Rajkhowa and Dr. D. Borah S. Chand Publishing

Practical Biology for Class XI is a focused laboratory manual tailored to the AHSEC syllabus (Assam Higher Secondary Education Council) and is published by S. Chand. Authored by renowned academicians Dr. R. C. Rajkhowa and Dr. D. Borah, the book is meticulously structured into two sections: Botany and Zoology. This concise paperback (approximately 79 pages) offers a clear, hands-on approach to mastering key practical techniques required for senior secondary biology.

In the Botany section, students engage in activities such as preparing and examining temporary slides of dicot and monocot roots and stems, studying osmotic phenomena, plasmolysis, stomatal distribution, transpiration rates, and pigment separation using paper chromatography. The Zoology portion includes qualitative tests for biochemical constituents (proteins, sugars, fats, urea, bile salts), microscopic study of blood and animal tissues, and spotter identification of common specimens like Amoeba, Hydra, Starfish, and Pigeon. Practical exercises also cover mitosis in onion root tips and essential investigatory projects.

The book’s strengths lie in its concise format, student-friendly language, and focus on core experimental skills—ideal for students seeking clarity without overwhelming detail. Priced affordably (around ₹200, though availability may vary), it’s a valuable companion for Assam board aspirants aiming to strengthen their laboratory competence.
