Q. Read the following statements and choose the correct option given below I. Major account of transpiration takes places through surface/margin of leaves II. A little amount of water is lost through stem, this is reffered 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 IV
D) II, III and IV
Explanation
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
