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 leave the cell and resulting in cell shrinkage.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Why can't ocean fish survive in freshwater?

Back

Freshwater is hypotonic to ocean fish cells, causing water to enter the cells, leading to swelling and potentially bursting.

Front

What does selectively permeable mean in relation to the cell membrane?

Back

Selectively permeable means that the cell membrane allows certain substances to pass while blocking others.

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 enter the cell and potentially leading to swelling.

Front

What is an 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 happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is diffusion?

Back

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

Front

What is the role of the cell membrane?

Back

The cell membrane protects the cell and regulates what enters and exits, maintaining homeostasis.
