Cell Transport

Front

What is passive transport?

Back

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

Front

Why is passive transport called 'passive'?

Back

It is called 'passive' because it occurs without energy.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows some substances to enter and leave the cell while keeping others out.

What happens to an animal cell in a hypertonic solution?

Back

The animal cell will shrink.

Front

What is a hypotonic solution?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solute compared to the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

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 role does the cell membrane play in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
