Osmosis

Question	Answer
Osmosis	movement of water molecules accross a semi-permeable membrane from a region of highwater concentration to a region of low water concentration.
Solvent	liquid the dissolved other substance
Solute	substance that has been dissolved
Solution	mixture of the solvent and solute in a solution
animal cell is in solution that is the same concentration as its cytoplasm	water will move in and out through its cell membrane at the same rate
Animal cell is in a solution that is less concentrated than the cell	gain water due to osmosis
animal cell is in a solution that is more concentrated than the cell	lose water due to osmosis
Amoeba	single-celled organism that lives in freshwater pools and ponds
osmoregulation system in amoeba	Contractile Vacuole
plant cell has a higher concentration of solutes than its surroundings	water moves into the cytoplasm and vacuole
Turgor Pressure	pressure in the cytoplasm and vacuole against the cell wall of a plant
cytoplasm of a plant cell has a lower concentration of solutes than the surrounding	water moves out of the cell
Plasmolysis	loss of water from the cytoplasm and the movement of the cell membrane away from the cell wall
