Osmosis

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of low concentration to an area of high concentration.

Front

What type of solution should cells ideally be in?

Back

Isotonic solution.

Front

What does water move towards during osmosis?

Back

Water moves from high to low concentration.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What happens to a blood cell in an isotonic solution?

Back

Water moves equally in and out of the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell.

Front

What occurs when a cell is placed in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What occurs when a cell is placed in a hypotonic solution?

Back

Water moves into the cell, causing it to swell and potentially burst.

Front

Define diffusion in the context of osmosis.

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
