Multiple Choice

Which statement describes the energy involved in diffusion?

• Diffusion requires energy in all cases.

• Diffusion requires energy only to move material in through the cell membrane.

• Diffusion does not require energy in any situation.

• Diffusion requires energy only to move material out through the cell membrane.

Multiple Select

Causes molecules to move until they are evenly distributed

–Moves from high concentration to low concentration

–Has no need for added energy

–Can occur with or without a membrane being present

• active Transport in Cells

• Passive Transport in Cells

• Osmosis

• diffusion

• it just moves

DIffusion

Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.

Multiple Choice

Which statement describes the movement of water when a cell shrinks and shrivels due to osmosis?

• Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.

• Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.

• The cell membrane used energy to move water into the cell through passive transport.

• The cell membrane used energy to move water out of the cell through passive transport.

Multiple Choice

what describes active transport

• Uses energy to work

• Moves from high concentration to low concentration

• Moves across the cell membrane
