What are the funtions of the cell membrane?

Answer 1

The cell membrane is the outer most layer of the cell, and its functions are as follows:

- Allows certain materials to enter the cell

- Gets rid of cell waste.

- Contains all the cell organelles.

- Protects the cell from injury

Answer 2

They have a few key roles.

1. Inter-cellular communication - eg. receptors for enzymes.

2. Transport: Proteins form transporters or channels, allowing substances to pass into and out of the cell. This can be passively (eg. aquaporins) or actively (the Na/K ATPase pump)

3. Immune functions - eg. antigens.

4. Structure. Some cells use proteins to maintain complex structures, as the phospholipid bilayer defaults to a simple spherical blob without them (and supporting carbohydrates of course)!

Answer 3

The cell membrane acts as a barrier that separates the internal environment of the cell from the external environment. It regulates the passage of substances in and out of the cell, helps maintain cell shape, and plays a role in cell recognition and communication. Additionally, the cell membrane houses receptors that allow cells to respond to external signals.

Answer 4

The main functions of the cell membrane is to allow or stop material from getting in or out of a cell.

Answer 5

It holds in and protects all of the cell's organelles

Answer 6

It act as the covering.It protects the cell.It regulates the entry and exit of materials.It regulates the communication among cells.

Answer 7

The cell membrane suuronds the cell beneath the cell wall. It protects the cell from harm and it produces cyctoplasm.

Answer 8

The cell membrane controls materials the comes in and out of the cell.
