Question

Differentiate between cell wall and plasma membrane

Answer 1

cell wall is a structural layer surrounding some types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. ... Cell walls are present in most prokaryotes (except mycoplasma bacteria), in algae, plants and fungi but rarely in other eukaryotes including animals.

plasma membrane is a microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and regulates the passage of molecules in and out of the cytoplasm.

Answer 2

Cell wall :-

• It is made up of complex carbohydrates called cellulose. It is dead or non living cell.
• It is found in plants cell only.
• It is permeable.
• It is hard and rigid.

Plasma membrane :-

• It is consisted of plasma proteins and lipids.It is living cell.
• It is found in both plant and animals cells.
• It is semi permeable.
• It is soft and elastic.
