Diffusion Osmosis

Which of the following has the highest water potential?

• distilled water

• 1% glucose solution

• 10% glucose solution

• 50% glucose solution

The movement of molecules (matter) from an area of greater concentration (how much of something) to an area of lower concentration. Does not require energy.

• Active Transport

• Passive Transport

• Osmosis

• Diffusion

The movement of water across a semi-permeable membrane through diffusion. (semi-permeable means lets some things in and not others)

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

Does NOT require energy....the movement of molecules (matter) from an area of high concentration to an area of low concentration. Diffusion is a kind of passive transport.

• Active Transport

• Passive Transport

• Osmosis

• Facilitated Diffusion

Channel proteins help polar substances enter/leave the cell. Does NOT require energy, so passive form of transport.

• Active Transport

• Passive Transport

• Osmosis

• Facilitated diffusion

The picture below is an example of _________________ .

• osmosis

• isotonic

• diffusion

• active transport

Which option best describes what osmosis is?

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of any particle from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of any particle from an area of low concentration to an area of high concentration

The cell below is shrinking. It can be concluded that the concentration of water is:

• higher inside the cell than outside the cell

• lower inside the cell than outside the cell

• the same inside and outside the cell

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.
