What is cellular transport?

Back

The process by which substances move in and out of cells, maintaining homeostasis.

What is the function of the cell membrane?

Back

It regulates what enters and exits the cell, providing protection and structure.

Front

Define hypertonic solution.

Back

A solution with a higher concentration of solutes compared to another solution, causing water to move out of the cell.

Front

Define hypotonic solution.

Back

A solution with a lower concentration of solutes compared to another solution, causing water to move into the cell.

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space or between two solutions.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and may shrivel due to the higher concentration of solutes outside.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst due to the lower concentration of solutes outside.

Front

What is osmosis?

Back

The movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy (ATP).
