This book is divided into four units and contains a total of 12 chapters. The first unit of this book deals with the fundamental concepts of matter, life, and energy. It has been a topic of concern to the man of all ages to know how and when life originated. Is it present only on the earth or also elsewhere This topic is discussed in the beginning of the first unit. The other topics included in this unit are cell as the basic structural and functional unit of life structure of prokaryotic and eukaryotic cell biomolecules and enzymes. The second unit of the book is related to diversity of life systems. In this section some important and basic aspects of plant system, animal system and microbial system are discussed. These three types of systems are necessary for the sustenance of the life on the planet earth.
