Question

difference between Semipermeable membrane and selectively permeable membrane​

Answer 1

Required Answer:-

Ya...Mostly we are confused these two terms while learning the concepts behind Osmosis. They are different in the following ways:

Semi-Permeable membrane:

• It allows the movement of solvent molecules only (depends on the size of molecule).

• Completely impermeable to solutes and larger molecules. Hence, It makes a perfect partition.

• Difficult to find in living organisms i.e. in the biosphere.

• This membrane is used as Dialysing membrane in Dialysis, maintaining turgidity etc.

Selectively-Permeable membrane:

• It allows the movement of solvent and some selectively chosen solute particles.

• It is not completely impermeable to solutes. It chooses them.

• Almost all types of biological membranes are of this type.

• Found in living organisms, it helps in maintaining turgidity $.$
