Cell Transport Review

Front

What process explains why wilted lettuce becomes crisp when placed in water?

Back

Osmosis allows water to move into the lettuce cells, making them turgid.

Front

What type of solution causes a cell to shrink in size?

Back

Hypertonic solution.

Front

What is the term for the movement of molecules against their concentration gradient, requiring energy?

Back

Active transport.

Front

What is the term for a solution with a lower concentration of solutes compared to the cell's interior?

Back

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell loses water and shrinks.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What type of transport occurs when molecules move from an area of high concentration to an area of low concentration?

Back

Passive transport.
