what is the different between the plasma membrane and cell wall? Give the function of each one
Answers
Answer: These membranes have a selective permeability which controls the transport of substances across the membrane.
What is a Cell membrane
The cell membrane is the outermost layer of the cell that surrounds the complete contents of a cell, including the endoplasmic reticulum, nucleus, cytoplasm, mitochondria, and all other organelles. It consists of a phospholipid bilayer and the integral proteins which provide pathways for the molecules to move through the membrane. In the animal cell, these cell membrane acts as the barrier between the inner contents of the cell and the external environment. The main function of a cell membrane includes, regulation of entry and exits within the cell, provides shape to the cell and ensures that the cell organelles do not flow away from the cell.
What is a Plasma membrane
The plasma membrane is an essential membrane of the cell which plays an important role in the separation of the interior organelles of the cells from the external environment. The plasma membrane is a tough, rigid and flexible layer, found surrounding the cellular compartments. They are mainly involved in the membranes formation of the other organelles and also controls the transportation of substances across the membrane. The plasma membranes have numerous functions and are mainly depended on their site of location.
