Question

a cell is placed in a solution containing oxygen, water, and large protein molecules. oxygen and water move into the cell easily, but the large protein molecules do not. which property of the cell membrane best explains this situation? image of cell membrane structure options: selective permeability, active transport, diffusion, osmosis

Explanation:

The problem is about the cell membrane's property that allows small molecules (oxygen, water) to enter but blocks large protein molecules. Selective permeability means the membrane allows certain substances to pass while restricting others. Active transport is energy - using movement against concentration, diffusion is random movement of particles, and osmosis is water diffusion. So selective permeability explains this.

Answer:

A. Selective permeability
