Answer:

once, my teacher told me "wow prathyusha, you are outstanding"

and I told my teacher "mam but I think you have to change Ur specs, because am not standing outside

Answer 2

CELL WALL:-----

1) Present only in plants and in some fungi, bacteria, algae.

2)It is the outermost part of the plant cell.

3)It is made up of pectin, chitin, lignin, glycoproteins, glycolipids, sugar, and cellulose.

4) The cell wall is 0.1 μm to several μm in thickness.

5) It is the thick and rigid structure with a fixed shape.

6) It protects the cell from the external environment.

7) The cell wall is metabolically inactive.

8) The cell wall grows in thickness over time. Further, it occupies the whole cell in the plant as the cell ages and dies.

9) The cell wall is fully permeable to smaller molecules with the size of 30-60 kDa.

10) Functions include protection from the external environment.

CELL MEMBRANE:----

1) Present in all types of cells, in humans, animals, plants, bacteria, etc.

2)It is the outermost covering the animal cells.

3) It is a lipid bilayer. And is composed of lipoproteins and carbohydrates.

4) The cell membrane is 7.5–10 nm in thickness.

5) It is a thin and delicate structure. It is flexible to change the shape as needed.

6) It protects and maintains the internal environment of the cell.

7) The cell membrane is metabolically active.

8) It is of the same thickness for the lifetime of the organism.

9) The membrane is selectively permeable and controls the movement of the substance into and outside the cell.

10) Functions include permeability, signal reception, motility conduction, cell division, sexual reproduction, etc.
