Cell Transport

Front

What are the two types of cell transport?

Back

Passive and Active

Front

In passive transport, substances move across the cell membrane ________ the concentration gradient.

Back

WITH

Front

Which describes a hypotonic environment?

Back

Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell.

Front

Which describes a hypertonic environment?

Back

Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell.

Front

The movement of particles from an area of high concentration to an area of low concentration is called?

Back

Diffusion

Front

What is osmosis?

Back

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

Front

What is active transport?

Back

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

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may burst.
