Key Differences:
-
Cell Wall in Plants:
- Plant cells have a strong outer layer called a cell wall. This wall is made from a material called cellulose.
- The cell wall helps plants stay upright and gives them shape.
- About 30% of a plant's weight comes from its cell wall.
- Plant cell walls can be between 0.1 to 1 micrometer thick.
-
No Cell Wall in Animal Cells:
- Animal cells do not have a cell wall. This gives them a more flexible shape.
- Instead, animal cells get their strength from a structure inside called the cytoskeleton. This helps them move and change their form.
- On average, animal cells are about 10 to 30 micrometers wide, which gives them room to be flexible.
Other Important Differences:
- Chloroplasts:
- Plant cells have chloroplasts to help them create food through a process called photosynthesis. Animal cells do not have chloroplasts.
- Vacuoles:
- Plant cells usually have one large vacuole that stores nutrients and helps keep the plant firm.
- Animal cells have many smaller vacuoles instead of one big one.
These differences show how plant and animal cells are suited to their different roles in nature.
