How do plants and animal cell
differ?
What is the difference between the
plant and animal cells?
1. cell wall
2. vacuole
3. chloroplast
1. Cell wall
CELL WALL- all plants have a cell wall.
Animal cells do not have a cell wall. A cell
wall surrounds the cell membrane of a
plant cell. The cell wall is made up of a
hard material called cellulose. Wood is
made up mostly of cellulose.
The cell wall has 3 jobs:
• protects the plant cell
• gives its shape
• supports the cell
2. Vacuoles
VACUOLES- Plant
cells have only one
or two very large
vacuoles. But
animal cells have
many small
vacuoles. When it
rains, plants will
store water in
vacuoles.
3. Chloroplasts
CHLOROPLASTS- most
plants have a green
round organelle called
chloroplast. Chloroplast
has chlorophyll which
gives a plant its green
color. Plants use
chlorophyll to make food
from the sun. Animals
have no chloroplasts.
Checking concepts: What are the
three jobs of a cell wall?
What is cellulose?
How do the vacuoles in animal cells
differ from those in plant cells?
What are chloroplasts?
Which one of the following organisms
contain cellulose: a pine tree, a cow, a
rabbit, a fern, a grass, a goldfish?
Large plants do not have a
skeleton or frame. How can large
plants stand without skeletons?
Fill in blanks.
1. All plants have ____________.
2. An organelle, called _________, has
chlorophyll that makes plant have a green
color.
3. Plant cells have ______ vacuoles, whereas
animal cells have __________ vacuoles.
4. Cellulose is made up of a hard material called
_____________.
5. Chloroplasts has a material called
______________ that gives a plant its green
color.
