Question

Four Hibiscus leaves (A,B C and D) are hung in a line. Vasline is applied on both surfaces of A, lower surface of B, upper surface of C and D is left without applying vasline. In which of the following order the witting of leaves will take place? (first wilting to last wilting)

• A. A-B-C-D
• B. B-A-D-C
• C. C-B-D-A
• D. D-C-B-A

Answer 1

The correct option is D D-C-B-A

Since no Vaseline is applied here the wilting will begin here, and since hibiscus is dicot the distribution of stomata is more on the lower surface, hence Vaseline on upper surface will not reduce water loss, both surfaces with Vaseline no transpiration.
