Biology 2.1.5 Cells in solutions of different water potentials
Flashcards do conjunto (13)
- 1Does a concentrated sugar solution have a high or low water potential?Lower
- 2What happens to a cell placed in a concentrated sugar solution (in terms of movement of water)?Water moves from an area of higher water potential inside the cell to an an area of lower water potential outside the cell (water moves out the cell)
- 3What happens as a result of animal cells losing water?The cell volume decreases
The inside of the cells concentration increases - 4What happens as a result of the cells contents concentration increasing?Metabollic reactions effected
- 5What happens to a cell placed in a solution with higher water potential (in terms of movement of water)?Water moves from an area of higher water potential outside the cell to an area of lower water potential inside the cell (water moves into the cell)
- 6What happens as a result of water moving into an animal cell?Pressure inside the cell increases
Lysis - 7What is crenation? Does it happen to animal or plant cells?When an animal cell shrivels
- 8What is lysis? Does it happen to animal or plant cells?When animal cells burst
- 9Why do animal cells burst and plant cells dont?Plant cells have a cell wall to prevent bursting and the animals fragile plamsa membrane can't handle the higher pressure in the animal cells
- 10What happens to plant cells when they lose water?Cell volume decreases
Plasmolysis - 11What is plasmolysis?When the cytoplasm and plasma membrane pull away from the cell wall
- 12What happens to a plant cell when water moves into the cell?The cell volume increases
Cell contents push on the cell wall
Cell becomes tirgid - 13What's happened to the cell when it becomes tirgid?The cell swells
