Osmosis and Diffusion Vocab Quiz

Holes in a cell or nuclear membrane that allow some substances to pass in and out but not others.

• Osmosis

• Homeostasis

• Selective Permeability

The liquid substance you add to a solute to make a solution.

• osmosis

• solute

• solvent

Diffusion of water and other substances across the cell membrane from high concentration to low concentration and does NOT require energy.

• diffusion

• osmosis

• passive transport

A solution with the SAME concentration of water and solutes inside and outside the cell--water can move in and out of the cell equally.

• hypertonic solution

• isotonic solution

• passive transport

The amount of solute particles in a given solvent--how strong or weak the solution is based on how much solute is added to the solvent.

• concentration

• solute

• solvent

The diffusion of WATER ONLY from an area of high concentration to an area of low concentration across a semipermeable membrane.

• facilitated diffusion

• osmosis

• passive transport

A solution that has a higher concentration of solute outside the cell than inside the cell--this causes water to flow OUT OF THE CELL by osmosis and the cell will SHRINK.

• osmosis

• hypertonic solution

• isotonic solution

The passive transport of ions and small molecules across the cell membrane using transport proteins.

• active transport

• facilitated diffusion

• osmosis

The substance you add to a solvent to make a solution.

• solute

• selective permeability

• solvent

When substances move across the cell membrane from low concentration to high concentration--DOES require energy.
