Main Functions Special Name

1 Cell wall • Surrounds and protects the cell
• Make the cell stiff and strong

Supporter and protector

2 Cell
membrane

• Holds and protects the cell
• Controls the movement of materials
in and out of the cell

Gate of the cell

3 Cytoplasm • A watery, gel-like material in which

cell parts move

Area of movement

4 Mitochondria • Produce and supply most of the

energy for the cell

Power house of the cell

5 Chloroplasts • Contain green pigment chlorophyll
• Capture the energy of sunlight and
use it to produce food for the cell by
photosynthesis.

Food producers for the
cell (Plant cell)

6 Vacuoles • Store food, water, and chemicals Storage tanks
7 Nucleus • Acts as ‘brain’ of the cell

• Regulates and controls all the cell
activities

Control centre

8 Nucleus
membrane

• Surrounds and protects the nucleus
control the movement of materials in
and out of the nucleus
