Osmosis and Diffusion Review

Front

What is the definition of a solute?

Back

A solute is the substance being dissolved in a solution.

Front

What direction do water molecules move during osmosis?

Back

Water molecules move out of the cell, causing the cell to shrink.

Front

Why should a person never drink salty water?

Back

Drinking salty water can cause cells to shrink due to osmosis.

Front

What happens to the cell wall and cell membrane in plant cells during osmosis?

Back

The cell wall stays the same, while the cell membrane shrinks.

Front

What occurs to an animal cell placed in a hypertonic solution?

Back

The animal cell will shrink and get smaller.

Front

Define osmosis.

Back

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

Front

What is 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 the inside of the cell.

Front

What is a hypotonic solution?

Back

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

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell.
