Cellular Transport Review

Front

What happens to cells placed in a hypotonic solution?

Back

Cells gain water (water moves in at a higher rate than it moves out).

Front

What must be true for diffusion to occur?

Back

There must be areas of different concentrations.

Front

What happens to cells placed in a hypertonic solution?

Back

Cells lose water (water moves out at a higher rate than it moves in).

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solute compared to another solution.

Front

What is the solute in a solution of sugar water?

Back

Sugar.

Front

Define diffusion.

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is an isotonic solution?

Back

A solution where the concentration of solute is the same as another solution.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solute compared to another solution.

Front

What role do protein channels play in cellular transport?

Back

They facilitate the movement of specific molecules across the cell membrane.
