Front

What is the process called when molecules move against a concentration gradient?

Back

Active transport.

Front

What type of solution causes water to enter a plant cell?

Back

Hypotonic solution.

Front

If an egg has shrunk, what type of solution was it placed in?

Back

Hypertonic solution.

Front

Osmosis is a form of what type of transport?

Back

Passive transport.

Front

What is the tonicity of a solution if water moves into the cell, causing it to swell?

Back

Hypotonic.

Front

Define tonicity in relation to cell transport.

Back

Tonicity refers to the ability of a solution to cause a cell to gain or lose water.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What is the primary driving force behind osmosis?

Back

The concentration gradient of water.

Front

What type of transport does not require energy?

Back

Passive transport.

Front

What is the effect of a hypotonic solution on animal cells?

Back

Animal cells may burst due to excess water intake.
