Passive Transport

Front

What is Passive Transport?

Back

Passive Transport is the movement of substances across a cell membrane without the use of energy by the cell.

Front

What does it mean when a cell is in Equilibrium?

Back

A cell is in Equilibrium when the concentration of water inside and outside the cell is the same.

Front

Define Permeable.

Back

Permeable means that things can pass through.

Front

What is Diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

Does Passive Transport require cell energy?

Back

No, Passive Transport does NOT require cell energy.

Front

What is Osmosis?

Back

Osmosis is a specific type of passive transport that involves the movement of water molecules across a semipermeable membrane.

Front

What is the difference between Active Transport and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not.

Front

Give an example of a substance that moves through Passive Transport.

Back

Oxygen and carbon dioxide can move through Passive Transport.

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.
