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?

• organs

• tissues

• cells

• organ systems

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

• active transport

• osmosis

• dissolving

• passive transport

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

• active transport

• diffusion

• cellular transport

• mitosis

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

• passive transport

• osmosis

• active transport

• respiration

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

• respiration

• passive transport

• active transport

• unicellular

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?

• active transport

• photosynthesis

• osmosis

• cellular respiration

Diffusion is defined as ---

• particles moving from an area of high concentration to an area of low concentration

• a process of moving something across a cell membrane that requires energy

• diffusion of water across a semipermeable membrane

The word "selectively permeable" means ---

• allows only certain substances to pass through

• not allowing anything to pass through

• allowing all substances to pass through

• none of the answers are correct

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

• in the flower

• in the leaves

• in the vase

• can not be determined by the picture
