Mind Map

Summary of Chapter 2 Cell Structure and Cell Organization 

Cell 

• Cell is the basic unit of life and is functioned to carry out the life processes. 
• It exists in various shapes and sizes. 
• It is made up of plasma membrane which contains protoplasm (cytoplasm and nucleus).
• The function of cell is to carry out the life processes. 

There are 2 types of cell:

Animal cell                             Plant cell 

Table below shows the similarities and differences between animal cell and plant cell:

similarities and differences between animal cell and plant cell

** density of organelles (specialized structures which are each surrounded by its own membrane & perform specific functions) in a cell depend on the type of cell and its function**

e.g. cells that are active have many mitochondria to provide enough energy for its activities:-

• Sperm cell
• Muscle cell
• Meristem cell

e.g. cells that have many chloroplast for photosynthesis:-

• Mesophyll cells
• Guard cells
