Parts of an animal cell!

This is the

brain of the

cell. It directs

all its activities.

This is the

jelly like

substance

inside the

cell.

These give

the cells

energy. They

release energy

in the cell.

This holds the cell

together and

separates it

from its surroundings.

These store food and

water in the cell.


Parts of a plant cell!

This holds the cell

together and

separates it

from its

surroundings.

This is the jelly like

substance inside the cell.

cytoplasm

cell

membrane

These store food and

water in the cell.

vacuoles

This is the

brain of the

cell. It directs

all its activities.

These give

the cells

energy. They

release energy

in the cell.

nucleus

mitochondria


Parts of a plant cell!

chloroplasts

This makes food

forthe plant cell.

This supports

and protects the plant cell!

cell wall

Remember, a plant cell has two other parts

that an animal cell does not have!

What are they?


circulatory
