When water goes into the cell and out of the cell are in equilibrium, then the solution and cell are respectively
(1) Isotonic, Flaccid
(2) Hypotonic, Flaccid
(3) Hypertonic, Turgid
(4) Hypotonic, Turgid
Plasmolysis is
(1) Usually reversible
(2) Occurs when cell is placed in hypotonic external solution
(3) Shrinkage of cytoplast
(4) All of these
When the cells are placed in a hypotonic solution water movement causes
(1) Osmotic pressure
(2) Turgor pressure
(3) Hydrostatic pressure
(4) Hydrodynamic pressure
Turgor pressure causes
