Question

13. how are the cell wall and the cell membrane similar? How are they different?

Answer 1

$\mathfrak{cell \ wall}$
The outer covering of plants outside the plasma membrane.

$\mathfrak{cell \ membrane}$
The outer covering of all cells except in plants.

The cell wall is a very rigid outer covering.
The cell membrane is very soft in cells with a cell wall.

Answer 2

Answer:

How are the cell wall and the cell membrane similar? How are they different?

Explanation:

• How cell wall and cell membrane is similar-
• Cell wall and cell membrane have in common that it is being a barrier and it provides structure and support for the cell.
• They both protect the cell interior from the external environment.

• How cell wall and cell membrane different-
• Cell wall is present only in plants and in some fungi for example- bacteria and algae. Cell wall is the outer most part of the plant cell. It is made up of pectin, chitin, sugar. The cell wall is thick and rigid. The cell wall is metabolically inactive. The cell wall is fully permeable to smaller molecules.
• Cell membrane is present in all types of cells, in humans, animals, plants, bacteria. It is the outer most covering in the animals cells. It is a lipid bilayer. It is thin and delicate structure. it is flexible to change the shape as needed. It protects and maintains the internal environment of the cell. the cell membrane is metabolically active.

Hence, this is similarity and difference between cell wall and cell membrane.
