OSMOSIS/DIFFUSION

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

During osmosis, what direction does water move?

Back

Water moves from an area of high concentration to an area of low concentration.

Front

What happens to a cell in a hypotonic environment?

Back

A cell in a hypotonic environment will swell as water moves into 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 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 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.

Front

What is isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What role does energy play in osmosis?

Back

Osmosis is a passive process and does not require energy; it occurs naturally due to concentration gradients.
