Cell Transport

Front

What does selectively-permeable mean?

Back

Allow certain things to enter and leave the cell.

Front

Which way will the water molecules move during osmosis?

Back

Out of the cell, so the cell shrinks.

Front

What is diffusion?

Back

The movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The process when WATER diffuses across a membrane.

Front

What is active transport?

Back

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

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is the same inside and outside the cell.

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrinks as water moves out of it.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells as water moves into it.

Front

What is the role of the cell membrane?

Back

To protect the cell and control what enters and leaves.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane proteins.
