Question

Structure and function of plasma membrane biology discussion

Answer 1

Structure of Plasma Membranes

The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Answer 2

Structure of Plasma Membrane:

1.The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment.

2.It is a fluid mosaic of lipids, proteins and carbohydrate.

3.The plasma membrane is impermeable to ions and most water-soluble molecules.

Functions of Plasma Membrane:

1. The primary function of the plasma membrane is to protect the cell from its surroundings.

2.The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues.

3.The membrane also maintains the cell potential.

4.The cell membrane interacts with the cell membrane of adjacent cells e.g. to form plant and animal tissues.
