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

Does passive transport require cell energy?

Back

No, passive transport does NOT require cell energy.

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

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 happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the cell, causing it to swell and potentially burst.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the cell, causing it to shrink.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

Can diffusion occur in both plants and animals?

Back

Yes, diffusion can occur in both plants and animals.

Front

What is the role of the cell membrane in passive transport?

Back

The cell membrane acts as a barrier that allows certain substances to pass through while keeping others out, facilitating passive transport.

Front

Give an example of a substance that moves by diffusion.

Back

Oxygen moves into cells by diffusion.
