Passive Transport Review

Front

What is passive transport?

Back

Passive transport is the movement of materials across the cell membrane that occurs without the use of energy.

Front

Why is passive transport called 'passive'?

Back

It is called 'passive' because it occurs without the use of energy.

What happens to blood cells in a hypertonic solution?

Back

Blood cells shrink in a hypertonic solution.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is selective permeability?

Back

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

Front

What does it mean if a membrane is permeable?

Back

If a membrane is permeable, it allows substances to pass through freely.

Front

What does it mean if a membrane is impermeable?

Back

If a membrane is impermeable, it does not allow any substances to pass through.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What does 'high concentration area' mean?

Back

A high concentration area means that the molecules are tightly packed together.
