The area of highest water potential is… The area of lowest water potential is… Therefore water moves… The animal cell is in a __________________ solution. The area of highest water potential is… The area of lowest water potential is… Therefore water moves… The animal cell is in a __________________ solution. The area of highest water potential is… The area of lowest water potential is… Therefore water moves… TURGID When you put cells into pure water or a solution that is not as concentrated as the cell’s cytoplasm then water moves by osmosis into the plant cell vacuole. The pressure of the added water causes the cell to swell. The cell becomes turgid. FLACCID When you put cells into a solution with the same concentration as the cell’s cytoplasm then water moves by osmosis into and out of the plant cell vacuole at the same rate. There is no added pressure caused by the movement of water and the cell doesn’t swell. The cell is called PLASMOLYSED When you put cells into a concentrated solution or a solution with a higher concentration than the cell’s cytoplasm then water moves by osmosis out of the plant cell vacuole. The loss of water from the vacuole decreases pressure in the cell and the cell membrane pulls away from the cell wall. The cell is plasmolysed. HAEMOLYSED When you put cells into pure water or a solution that is not as concentrated as the cell’s cytoplasm then water moves by osmosis into the cell. The pressure of the added water causes the cell to swell. The cell becomes turgid and eventually the cell membrane splits, this is haemolysis (cell dies!) NORMAL When you put cells into a solution with the same concentration as the cell’s cytoplasm then water moves by osmosis into and out of the cell membrane at the same rate. There is no added pressure caused by the movement of water and the cell doesn’t swell. The cell is normal. CRENATION When you put cells into a concentrated solution or a solution with a higher concentration than the cell’s cytoplasm then water moves by osmosis out of the cell membrane. The loss of water from the cell decreases pressure in the cell and the cell begins to shrink. The cells are plasmolysed (crenated).
