3. 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.

Remember, a plant cell has two other parts
that an animal cell does not have!
What are they?
