OSMOSIS/DIFFUSION

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What does passive transport require?

Back

Passive transport requires no energy.

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane regulates what enters and leaves a cell.

Front

What happens to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will shrink (get smaller).

Front

What type of solution is a cell in if it is hypertonic?

Back

The cell is in a hypertonic solution.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.

Front

What is concentration gradient?

Back

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