A substance in which another substance is dissolved

• solvent

• solute

• isotonic

• hypertonic

Energy requiring process by which substances move across the plasma membrane against a concentration gradient.

• active transport

• endocytoisis

• exocytosis

• facilitated diffusion

Plasma membrane layers composed of phospholipid molecules arranged with polar heads facing the outside and non-polar tail facing the inside.

• semipermeable membrane

• hydrophobic

• phospholipid bilayer

• hypotonic

A solution that has a lower concentration of solute outside than inside the cell, causing water to flow into the cell by osmosis

• hypotonic

• hypertonic

• isotonic

• osmosis

Net movement of particles from an area of higher concentration to an area of lower concentration without the use of proteins.

• passive transport

• facilitated diffusion

• simple diffusion

• osmosis

Fear of water, not liking water, staying away from water.

• hydrophobic

• hydrophilic

• isotonic

• hypotonic

Energy requiring process by which a cell expels wastes and secretes substances at the plasma membrane.

• endocytosis

• exocytosis

• osmosis

• facilitated diffusion

A solution that has a higher concentration of solute outside than inside a cell, causing water to leave the cell by osmosis

• hypotonic

• isotonoic

• hydrophilic

• hypertonic

A substance that is dissolved in a solvent.
