Water Balance in Cells

Isotonic

A plant cell surrounded by a(n) ___ solution will be flaccid (limp).

Diffusion

What is the movement of particles down their concentration gradient?

Water crosses the plasma membrane

through facilitated diffusion or diffusion

Hypotonic

An animal cell placed in a(n) ____ solution will gain water, swell, and possibly burst.

Facilitated diffusion

molecule moves down its concentration gradient using a transport protein in the plasma membrane.

Hypertonic

There is a net diffusion of water out of an animal cell when it is placed in a(n) ___ solution.

Hypotonic

The ideal osmotic environment for a plant cell is a(n) ___ environment.

Isotonic

The ideal osmotic environment for an animal cell is a(n) ____ environment.

Hypertonic

A plant cell placed in a(n) ___ solution will lose water and plasmolyze.

In active transport,

molecules move across the plasma membrane against their concentration gradient
