Question

When both water and salts are present in a solution and the cell needs water, which process enables the cell to obtain the water without the salt?

Question 1 options:

osmosis through a permeable membrane


diffusion through a permeable membrane


osmosis through a semipermeable membrane


diffusion through a nuclear membrane

Answer 1

The correct answer is:

**osmosis through a semipermeable membrane**

Osmosis is the process by which water moves through a semipermeable membrane from an area of lower solute concentration (more water) to an area of higher solute concentration (less water) in order to equalize the concentrations on both sides. In this case, the semipermeable membrane allows water to pass through while preventing the salts from doing so.
