Cellular Transport: Diffusion & Osmosis

Jackson is growing a bean plant in a pot. One day he notices the plant is wilting. He waters it and notices that even within a few minutes, it begins to perk up. This is because the plant has taken water into its central vacuoles through osmosis. At what level does osmosis occur?

Which term refers to the movement of water through a selectively permeable membrane (such as a cell membrane)?

Which term refers to the movement of a substance from an area of higher concentration to an area of lower concentration?

What is it called when energy is needed to move materials through a cell membrane?

What is it called when substances can pass through a cell membrane without any extra energy? (diffusion and osmosis are examples)

If plants do not get watered, they will start to wilt because their central vacuoles are empty. When they get water again, they will stand back up because their vacuoles have filled back up. What process allows their vacuoles to fill back up with water?

Diffusion is defined as ---

The word "selectively permeable" means ---

Look at the picture. Where is the highest concentration of water?

The image shows a model of which process?
