Life processes is a very important chapter. Each of the life process is important. Both the structure of the body system involved in the life process as well as the way the process is carried out is important. Even the activities related to photosynthesis are important.

The diagrams are a crucial part of the chapter. You need to practice them a lot to gain mastery over them. The theory of the figures should be understood before you attempt to draw the diagram. Then you will find the diagrams easier to draw.
