Question

What does the term semipermeable mean?

Answer 1

A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial.

Step-by-step explanation:

• Basically a barrier can be penetrated by certain things and not others.
• A semipermeable membrane, also termed a selectively permeable membrane, a partially permeable membrane or a differentially permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized "facilitated diffusion".
• It is a biological membrane, which functions by permitting the movements of certain molecules or ions to pass through it. It is a barrier that will only allow some molecules to pass through while blocking the passage of other molecules.
• Partially but not freely or entirely permeable. especially permeable to some usually small molecules but not to other usually larger particles. semi permeability.

Answer 2

(of a material or membrane) allowing certain substances to pass through it but not others, especially allowing the passage of a solvent but not of certain solutes.
