Question

Assertion : A cell requires water, minerals etc. to stay alive and function efficiently.

But every cell has cell membrane.

Reason : The movement of substances is through cell membrane that has tiny

pores for the movement of some substances for this reason this is called

selectively permeable.

​

Answer 1

Answer:

. Plasma/Cell membrane: This is the outermost covering of the cell that separates the contents of the cell from its external environment. The plasma membrane allows or permits the entry and exit of some materials in and out of the cell so the cell membrane is called a selectively permeable membrane. Some substances like CO2 or O2 gases can move across the cell membrane by a process called diffusion.

. Cell wall (Protective wall): Plants cells, in addition to the plasma membrane have another rigid outer covering called cell wall. The cell wall lies outside the plasma membrane.
