Biology - Osmosis/Diffusion

Front

What happens to an animal cell when placed in a hypertonic solution?

Back

The animal cell will shrink.

Front

Define osmosis in relation to diffusion.

Back

Osmosis is a type of diffusion specifically referring to the movement of water across a semipermeable membrane.

Front

What is the primary substance that moves during osmosis?

Back

Water.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

During osmosis, where does water move in terms of concentration?

Back

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

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside 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.

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell.

Front

How does osmosis differ from diffusion?

Back

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

Front

What role do semipermeable membranes play in osmosis?

Back

Semipermeable membranes allow only certain molecules, like water, to pass through while blocking others.
