Answer 1

Answer:

Plasma membrane:

• Protects the cell by acting like a barrier.
• regulates the transport of substances in or out of the cell.
• Receives chemical messages from other cells.
• It acts as a receptor.
• Cell mobility, absorption and secretions of substances
• They keep toxic substances of the cell.
• The flexibility of the membrane allows the cell to survive in different environments

Answer 2

Answer:

➡️The plasma membrane provides structural support to the cell.

➡️It surrounds all cells and physically separates the cytoplasm, which is the material that makes up the cell, from the extracellular fluid outside the cell.

➡️It provides additional support to the cell, and it is why plant cells do not burst like animal cells do if too much water diffuses into them.

➡️Plasma membranes are selectively permeable or semi-permeable(certain molecules only pass through them).

➡️The plasma membrane allows fluid to pass between the extracellular fluid and the cytoplasm.
