Osmosis vs. Diffusion Flashcard Review

Front

What regulates what enters and leaves a cell?

Back

Cell Membrane

Front

What happens to wilted lettuce placed in cool water?

Back

Water moves into the lettuce cells by osmosis, making it crisp and firm.

Front

What does equilibrium mean?

Back

Equilibrium means balance.

Front

What does passive transport require?

Back

Passive transport requires no energy.

Front

What happens to an animal cell in a hypertonic solution?

Back

The cell shrinks (gets smaller).

Front

Define osmosis.

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Define diffusion.

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as another solution.
