The cell wall
It is used for protection against the outside environment
Cell Wall
you have a cell wall and cell membrane
The cell membrane on an animal cell is the outermost layer and acts as a protection shield. It is selectively permeable meaning it only lets certain things into the cytoplasm of the cell. The nucleus does not have a cell membrane, it simply directs the cells activities. In a plant cell there is a cell wall on the outside of the cell membrane giving the cell support and protection, but the cell membrane still provides the same function as it does on the animal cell. Post further questions if necessary! :)
cell wall
ok, ok -- Cell membrane -- separates whats on the outside of the cell -from whats on the inside of the cell, and controls what goes in and out Cell Wall- is found outside the cell membrane and provides these cells with structural support and protection. ~THE END. thats all i can give you
This is the cell wall. In bacteria it is made of peptidoglycan and in plants it is made of cellulose.
The nictitating membrane is the transparent layer the covers the outside of a frogs eye. Frogs have a so-called Nictitating membrane, which they can slide over their eyes for protection. They do this while jumping and swimming.
The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection, and also acts as a filtering mechanism.
The exoskeleton provides support for the plasmalemma, as does various proteins.
the cell membrane allows materials, such as bacteria, to come in or out.It is the outside boundary of the cell that separates the cell from its envornment.
They have a rigid cell wall outside of the cell membrane.
