Osmosis and Diffusion

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

Which way do water molecules move during osmosis?

Back

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

Front

What is the movement of water across a membrane called?

Back

The movement of water across a membrane is called osmosis.

Front

What is Selective Permeability?

Back

Selective Permeability is the ability of the cell membrane to allow some things to pass through while preventing others.

Front

What are Diffusion and Osmosis examples of?

Back

Diffusion and Osmosis are examples of Passive Transport.

Front

What is Diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What type of transport requires energy?

Back

Active Transport requires energy.

Front

What type of transport does not require energy?

Back

Passive Transport does not require energy.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell.
