Which of the following statements are correct/wrong?
a) A large quantity of water loss occurs through cuticleb) Lenticular transpiration is insignificant as compared to stomatal transpiration
c) Stomata are minute pores found on epidermal surfaces of leaves
d) Guttation occurs only in dry conditions
-
(a) and (b) are correct
-
(c) and (d) are correct
-
(b) and (c) are wrong
-
(a) and (d) are wrong
D
Correct answer
Explanation
Cuticular transpiration is minimal, not large, because the cuticle is a waxy waterproof layer. Lenticular transpiration is indeed insignificant (less than 1%) compared to stomatal transpiration (90%+). Stomata are correctly described as minute pores on leaf epidermis. Guttation occurs in high humidity/soil moisture conditions, not dry conditions - it happens when transpiration is limited but root pressure continues.
