Question

Explain the significance of a double-layered membrane for a cell.​

Answer 1

Significance of double-layered cell membrane:

• The double-layered cell membrane is a biological membrane also known as the plasma membrane.

• The cell membrane separates the cytoplasm from its surrounding environment.

• It is selectively permeable to the cell wall. It will keep the toxic substances out of the cell.

• It plays an important role in cytoskeleton formation. It gives shape and structure to the cell.

• The cell membrane maintains the cell potential and it plays an important role in cell signaling and communication.

Answer 2

Double layered membrane for a cell.

Explanation:

• The double layered membrane for a cell is known as Plasma membrane.
• It is a double layer of proteins and lipids that surrounds a cell and separates the cytoplasm from its surrounding environment.

• It is selectively permeable. It means that it allows only certain molecules to enter and exit.

• It controls the amount of some substances that go in or out of the cell.
• The inner membrane forms an outer boundary of the cell and it holds the cell together.
• The membrane is pliable, which means it can move and flex in response to the environment.
