Passive Transport

Front

What is Osmosis?

Back

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

Front

What does it mean when a cell has reached Equilibrium?

Back

It means that both inside and outside of a cell have the same amount of water.

Front

Define Selective Permeability.

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What is Equilibrium in the context of cell membranes?

Back

Equal amount of substance on either side of the membrane.

Front

In which organisms can Diffusion occur?

Back

Plants and Animals.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is the difference between Osmosis and Diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of particles.

Front

What role does a semi-permeable membrane play in Osmosis?

Back

It allows water to pass through while restricting the movement of certain solutes.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst.
