Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing water to enter the cell, leading it to swell.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will swell as water moves into it.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of a cell, resulting in no net movement of water.

Front

What happens to a cell in an isotonic solution?

Back

The cell stays the same size as water moves in and out at equal rates.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of a cell, causing water to leave the cell, leading it to shrink.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water moves out of it.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane help transport large molecules across the membrane and facilitate communication.

Front

What role do carbohydrates play in the cell membrane?

Back

Carbohydrates on the cell membrane receive messages from the body and help in cell recognition.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's structure and maintain its fluidity.
