Comprehensive Laboratory Manual In Biology For Class-XI

The present book entitled ‘‘Comprehensive Laboratory Manual in Biology’’ is meant for Class XI under 10 + 2 pattern of Central Board of Secondary Education. The subject matter of the book has been written in accordance with the latest syllabi prescribed by the CBSE and other boards of secondary education. The book has been designed as a reference rather than a copy of the instruments.

• The Subject Matter Has Been Written In A Simple And Lucid Language.

• A Brief Information About Theoretical Aspect Of The Experiments Has Been Given In The Beginning Of Each Experiment.

• Each Experiment Has Been Fairly Illustrated With All Possible Details.

• A Number Of Viva Voce Questions Have Been Given At The End Of Each Experiment.

It Is Confidently Hoped That The Book Will Serve As A Faithful Guide And Will Help The Students To Understand The Practicals In a Better Way.
