Cell Transport Test

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

The cell swells as water moves into it.

The cell shrinks as water moves out of it.

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

A concentration gradient is the difference in the concentration of a substance across a space.

There is a low concentration of dye at the bottom of the cup.

The egg gains water and swells.

A semi-permeable membrane allows water to pass through while preventing certain solutes from crossing.

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.
