Question

The cell membrane controls the traffic of molecules into and out of the cell, prevents the entry of toxic material into the cell and permits selective uptake of nutrients. Which property of the membrane can this be attributed to? A) Carbohydrates present on the membrane B) Lipid bilayer of the membrane C) Membrane fluidity D) Semi-permeable nature of the membrane

Answer 1

It is a semi-permeable / selectively permeable membrane that can be attributed to the cell's ability to controls the traffic the flow of molecules into and out of the cell, to prevent the entry of toxic materials into the cell and to permit selective uptake of nutrients.

Answer 2

Semi-permeable nature of the membrane.

Step-by-step explanation:

The semi-permeable nature of the membrane allows it to selectively allow some molecules to pass through the membrane while preventing others.

This is beneficial as this inhibits the toxic materials from passing through the cell and only allows molecules of up to a certain size to pass through.

The membrane is made up of proteins, phospholipids, and carbohydrates. This unique composition of the membrane only allows small molecules such as carbon dioxide and oxygen to pass through.
