(b) Transpiration/स्वेद
(c) Absorption/अवशोषण
(d) Respiration/श्वसन
Show Answer
Ans.(b)
Sol. Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant.
