Question

6. A plant cell may burst when
(a) turgor pressure equalises wall pressure
(b) turgor pressure exceeds wall pressure
(c) wall pressure exceeds turgor pressure
(d) None of the above​

Answer 1

Explanation:

(d) None of the above

When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
