10th class biology PDF by Punjab textbook board.
Biology is one of the major courses for matric students. The 10th class biology book is a perpetuation of the 9th class biology book. However, this book is relatively easy, dealing with the major concepts of biology. It has a total of nine chapters. The first six chapters are about the human body and its basic functions. Such as respiration, reproduction, and circulation. The remaining three chapters are about the major branches of biology.
The book is designed as semi-complex literature of biology. It may look like a difficult book, with many diagrams, but who can learn biology without knowing what is called what? Worry not; going through biology is the easiest if you are eager to understand what is going inside your body and how the things around you will impact your body.
What is inside the book?
This book is an amalgam of interesting facts and revelation. It will be a bumpy ride, but each chapter is important, and skipping any of these will be a loss for the learner. One more thing, unlike the other books, which you will come across for the 10th class, each chapter in the biology 10th class book by PTBB is different from others.
Even if a student starts studying from the middle of the book, it will still make sense as each chapter deals with an entirely independent concept. That is why it is very easy to cram the book; one more thing, the entire book is crammable; you can learn by heart every detail and still score the highest marks. However, if you want to pass the entry tests, it is better to consider the concepts.
