What is osmosis?

Back

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

Front

What does water move during osmosis?

Back

Water moves from high to low concentration.

Front

What is diffusion?

Back

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

Front

What is passive transport?

Back

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

Front

What is selective permeability?

Back

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

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane is a barrier that allows certain substances to pass while preventing others.

Front

What is the difference between osmosis and diffusion?

Back

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

Front

What is an isotonic solution?

Back

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

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 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.
