3.3 - Cell Transport

Front

What is equilibrium?

Back

Equal amount of substance on either side of the membrane.

Front

How many diamond molecules need to move to reach equilibrium?

Back

There is no net movement because the molecules are at equilibrium.

Front

Which way will the water molecules move during osmosis?

Back

Out of the cell, so the cell shrinks.

Front

Where is the lowest concentration of dye?

Back

At the bottom of the cup.

Front

What is the definition of Osmosis?

Back

The movement of WATER molecules across the cell membrane.

Front

What is diffusion?

Back

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

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 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 isotonic solution?

Back

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