CBSE Diagrams for Class 7
In class 7, there are 10 biology chapters are included. Most of the times students face difficulty in understanding the biology topics due to the terms are more complex and less diagrams are given in the chapter. Therefore we’re mainly concerns with the diagrams of biology and make them easy to understand. In this class 12 most important diagrams are included which are important from exam point of view also. Lets discuss about the diagrams.
Chapter 1 : Nutrition in plants –
From this chapter the most asked question is photosynthesis and how plants carried out photosynthesis so we make it easy by diagrammatically showing the diagram of photosynthesis.
Figure 1: Diagram showing photosynthesis
Chapter 2: Nutrition in animals –
In this chapter 2 diagrams are important in which first one is human digestive system, by this diagram students come to know parts of digestive system and location of the each part of digestive system. Next diagram included in the chapter is amoeba. It is the most interesting part that how amoeba a single celled organism get its nutrition. So, we make to easy to understand by diagram.

Chapter 9: Soil-
In soil chapter, the soil layer diagram is included. By which students can understand the how soil and layer of soil get formed.

Chapter 10 : Respiration in organisms :
In this chapter, how living organisms respire and exchange the gases through respiratory system is described. To understand this mechanism of breathing is important and respiratory system is vital. It gives idea about the parts of respiratory system and in which sequence this parts work.

Figure 6: Respiratory System
Chapter 11 : Transportation in animals and plants –
This chapter has equal importance with another chapters because it includes the transportation in animals and plants and how it is carried out. For this purpose the first diagram included in the chapter is diagram showing circulation by which blood circulation can be understand. The next diagram is included is the heart because all working of the body is through the heart. After the circulation and heart the human excretory system diagram has been added.

Chapter 12 : Reproduction in plants : In this chapter mainly reproduction in yeast by budding is important, therefore we’ve included the reproduction in yeast by budding is included. The reproduction in plant is carried out by pollination. So pollination diagram is drawn.

Chapter 18 : Waste water story
This is the last biology chapter giving information about waste water. one diagram is included in this chapter is drip irrigation in field.
