Question

What is one difference between a cell wall and cell membrane

Answer 1

A cell wall is a structural layer covering some types of cells. It is the external covering of plant cell.

It is tough, rigid or sometimes flexible in nature. It acts as the structural support and also provides protection to the plant by performing the filtering mechanism. Cell wall is made of different composition , like plants have cell wall made up of cellulose.

Cell membrane or the cytoplasmic membrane is a biological membrane that is made up of lipid bi layer with embedded proteins. It is selectively permeable.

Answer 2

The correct answer is:

a cell wall is only included on the plant cell

the cell membrane is included in both plant and animal cells

Step-by-step explanation:

The cell wall is the outer most integument of the cell. The cell wall covers the cell membrane. The cell membrane is also known as the plasma membrane or plasmalemma. There is no another name for the cell wall. The cell membrane is being in almost all types of cells.

The purpose of the cell membrane is the equivalent as that of the skin. It leaves the elements inside the cell from the outside. The cell membrane provides assistance to the cytoskeleton of the cell, gives shape to the cell, and helps in the formation of tissues by adding the matrix located in the extracellular. It allows the passage of a certain substance.A cell membrane is incorporated by the cell wall which forms the outer most integument.
