Discuss structure and function of organelles of mature cell(20marks)​

There are five main types of cell organelles:

Nucleus, cytoplasm, chloroplasts, cell membrane and cell wall.

Function of nucleus: Stores information needed for the cell to work

Function of cytoplasm: All chemical reactions in the cell takes place here.

Function of chloroplasts: Absorbs light energy to be used in photosynthesis

Function of cell membrane: Controls what goes into and out of the cell

Function of cell wall: Gives cells their shape and prevents cells from bursting due to osmosis

*Animal cells do not have chloroplasts and cell walls.
