diffusion and osmosis

The diffusion of water across a selectively permeable membrane is

Check all forms of cell transport that do NOT require energy

• diffusion

• passive transport

• active transport

• osmosis

Check all factors that have an effect on the rate of diffusion

• temperature

• concentration gradient

• surface area

• energy supply

If I have a beaker of squash, and I put very little squash in the beaker and lots of water, is the concentration of squash dilute or concentrated?

• Dilute

• Concentrated

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out

• There is no water

In an osmosis experiment, four potato strips, each 5 cm in length, were left in salt solutions of different concentrations. The table shows the lengths of the strips after 30 minutes. Which salt solution was the most concentrated? 

• A
• B
• C
• D

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

Solutes in a solution will continue to diffuse until ....

• they get old and worn out

• they lose their charges

• they are equally dispersed.

• they become too small

I placed a drop of blue ink into a test tube full of jelly. What process explains what will happen next?

• Transpiration

• Diffusion

• Osmosis

• Active Transport

If I have a beaker of squash, and I put lots of squash in the beaker and very little water, is the concentration of squash dilute or concentrated?

• Dilute

• Concentrated
