Question

Why is plasma membrane called a limiting membrane?​

Answer 1

Answer:

The cell membrane is a thin layer of protein and fat that surrounds the cell. These cell membranes are semi-permeable meaning they allow only some substances to pa.ss into the cell while blo.ck.ing others.

Answer 2

Plasma Membrane

• The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment

• The plasma membrane consists of a lipid bilayer that is semipermeable

• The plasma membrane regulates the transport of materials entering and exiting the cell

• The plasma membrane permits the movement of only certain molecules in and out of the cells

• It allows hydrophobic molecules and small polar molecules diffuse through the lipid layer, but does not allow ions and large polar molecules cannot diffuse through the membrane.

• due to these reasons , plasma membrane is called as a limiting membrane or selectively permeable membrane.
