CBSE Diagrams for Class 8
In class 8, there are basically 7 biology chapters are included. Out of this 7 chapters diagrams we have drawn main important ten diagrams. All the diagrams are neat labeled and asked in exam for 5 marks. These diagrams give full marks in exam if draw properly.
Chapter 1 : Crop production and management-
This chapter teaches us the techniques and accurate management of plants. To show the techniques 3 diagrams are included in which first is the seed drill and second is the plough, third included diagram is of Nitrogen cycle. By observing these diagrams students get better knowledge about farm and crop production. The neat labeled Nitrogen cycle diagram tells us the importance of nitrogen gas in the environment and which one is the usable form of nitrogen and non-usable form og nitrogen.

Chapter 8: Cell Structure and function-
Every living organism on the earth made from tiny cell. Therefore it is the basic question in every student’s mind that what is the concept of cell and how it looks a like. Therefore we’ve drawn the plant cell diagram and animal cell diagram. The plant cell and an animal cell structure are different so students can easily distinguish between two types of cells.

Chapter 9: Reproduction in animals-
This is one of the complex topic considered by students, due to terms and different concepts are involved in this. Reproduction in animals basically divided into 2 parts such as male reproductive system and female reproductive system. Both the system are completely different, so to avoid confusion we have provided the diagrams of male reproductive system and female reproductive system. Along with this the major topic included in this syllabus is life cycle of frog. The life cycle of frog tells us the stages of life of frog. The next diagram is Binary fission in amoeba is drawn in which how amoeba reproduces gave us.

Chapter 10: Reaching the age of adolescence-
This chapter included in the syllabus of class 8. It tells us how the physical and mental changes takes place during the age of adolescence. These changes occurs due to the hormonal changes in the body, to understand the hormones in the body we’ve drawn the diagram of Position of endocrine gland in human body.Thereforestudents can observe the location of endocrine glands and by which gland which hormone is secreting.

These are the 10 important diagrams included in class 8 biology.
