What does plasma membrane do in an animal cell?

Answer 1

The plasma membrane, or cell membrane, had many purposes, including:

-selective permeability (it controls what goes in and out of the cell)
-containing the cytoplasm (and therefore allowing chemical reactions to occur)
- offering limited protection to the cell, contrary to popular belief

Answer 2

the plasma membrane is responsible for exchange of nutrients and oxygen through the cell membrane. And responsible for filtering and keeping out dangerous pollutants.
it also gives the cell structure and shape in addition to providing protection.

Answer 3

plasma membrane in animal cell have many functions which r under:

1-it protects the cell from outside any activity.

2-it give shape to the cell.

3-its main function is to transport food particles nd water nd fluid to inside nd outside the cell.

4-it give support nd frame work to the cell.

5-many orgenells r bounded with cell membrane or plasma membrane during invagination process.

6-it maintains osmotic pressure,turgor pressure,water potential nd maintain the environment of the cell .

7-it works during exocytosis nd endocytosis.

8-it works during hypotonic nd hypertonic environment.
