Question

. What is a cell membrane? Why it is important to a cell?​

Answer 1

Answer:

Cell membranes contain and protect the contents of the cell. They are active in signaling other cells, and proteins embedded in their matrix regulate the cell's chemistry by selectively absorbing and secreting chemicals.

Answer 2

Answer:

All living cells contain a cell membrane, the semipermeable structure that surrounds the cell. This flexible ability is important because it allows the cell to survive in differing environments, such as when immersed in water over long periods of time.
