Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

The picture below is an example of _________________ .

• osmosis

• isotonic

• diffusion

• active transport

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.

• Out of the cell, so the cell swells.

• Into the cell, so the cell shrinks.

• Into the cell, so the cell swells.

If a red blood cell is put in distilled water, what will most likely happen to the cell?

• Nothing will happen

• It will shrivel.

• It will burst and then shrivel up

• It will swell and burst

In the given scenario what will happen?  An egg is placed in pure water for 48 hours.

• The egg will gain water and swell.

• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.

• The egg will lose water and shrink.

Ideally, your cells should be in a(n) _______ solution

• Hypertonic

• Hypotonic

• Isotonic

• Cola

_______ regulates what enters and leaves a cell.  

• Cell Membrane

• Nucleus

• Mitochondria

• Cytoplasm
