| (i) Surface/margin of leaves is a major area for transpiration. |
| (ii) Little amount of water is lost through stem, this is referred to cauline transpiration. |
| (iii) Transpiration is comparatively a slow process then evaporation. |
| (iv) Transpiration driven ascent of sap does not depend on cohesion, adhesion and surface tension properties of water |
A) (i), (ii),(iii) and (iv)
B) (i), (iii) and (ii)
C) (i), (ii) and (iii)
D) (ii), (iii) and (iv)
Correct Answer: B
Solution :
[b] An account of 90% total transpiration occurs through leaves, i.e. foliar. Remaining 10% takes place through stem, flower and fruits etc. Cauline transpiration is the loss of water from stem. Ascent of sap in conducting tissues of plant is affected by cohesion, adhesion and properties of water.
