What is osmosis?

Back

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

Front

What is diffusion?

Back

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

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

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the diffusion of water, while diffusion refers to the movement of any type of particles.

Front

What happens to cells in a hypotonic solution?

Back

Cells placed in a hypotonic solution will swell and may burst due to the influx of water.

Front

What happens to cells in a hypertonic solution?

Back

Cells placed in a hypertonic solution will shrink as water moves out of the cell.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain molecules to pass through while blocking others.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, including diffusion and osmosis.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water entering the cell.
