Transport-In-Plants Question 31
Question: Read the following statements and choose the correct option given below:
(i) Surface/margin of leaves is a major area for transpiration. (ii) Little amount of water is lost through stem, this is referred to as cauline transpiration. (iii) Transpiration is comparatively a slow process than evaporation. (iv) Transpiration driven ascent of sap depends on cohesion, adhesion and surface tension properties of water
Options:
A) (i), (ii), (iii) and (iv)
B) (ii), (iii) and (i)
C) (i), (ii) and (iii)
D) (ii), (iii) and (iv)

Answer:
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.
Cauline transpiration is the loss of water from leaves.
Ascent of sap in conducting tissues of plant is affected by cohesion, adhesion and properties of water.
