CELLS: What are they?
AKS: 13 identify the cell as the building block of living organism
13b compare and contrast animal and plant cells
Cells are the tiny building blocks
that make up all living things.
What is the difference between an
animal cell and a plant cell?
• Both animal and plant cells have tiny organelles or

•
parts inside them.
Here are the parts you need to know: cell membrane,
cell wall, cytoplasm, nucleus, and chloroplasts.
The cell membrane protects the cell and controls
what substances enter and leave it.
The nucleus is the cell’s control center. Genetic
information is stored in the nucleus.
The cell wall gives the plant cell a stiff, rigid box-like
shape.
Cytoplasm is the area between the cell membrane and
the nucleus; it contains a gel-like fluid where the
other organelles move around in.
Chloroplasts capture energy from the sun and use it
to manufacture its food, glucose.

What are the two different shapes
that you see in the plant and
animal cell models?
• PLANT CELLS are shaped like boxes or
SQUARES.
• ANIMAL CELLS are circular or round.
What TWO organelles do plant cells have, but animal cells DO NOT? WHY?
CHLOROPLASTS AND A CELL WALL
•Plants make their own food inside the chloroplasts.
•The cell wall helps create and maintain structure for
the plant’s stem or trunk.
