Textbook Question
Chapter 6, Problem 4DQ
If two leaves are removed from a plant and one is coated with petroleum jelly, while the other is not, the uncoated leaf will shrivel considerably sooner than the coated one. Would it be helpful to coat the stems of young trees with petroleum jelly? Explain.

Answefr the following questions:
a.) How many cells thick is the upper epidermis in the leaf structure?
b.) Does this layer contain choloroplast?
c.) Do cells of the lower epidermis contain chloroplast?
Leaves of a healthy potted plant were coated with petroleum jelly. How will it affect the plant? State two reasons.
two leaves A and B, each having the petiole in a closed test tube full of water. Each is hung on a spring balance. Leaf A has a waxy cuticle on the upper epidermis and stomata on the lower epidermis. Leaf B a waxy cuticle on the upper epidermis and a lower epidermis covered with petroleum jelly. Both leaves were cut from the same plant.
i)Explain why it is important for the leaves to be cut from the same plant.
(ii) List TWO variabes that must be kept constant in this investigation. iii) Table 6 shows the results obtained in the experiment:
leaf and test tube
weight
final weight
change in weight
A
40.7

38.7
0.0
Explain why the weight of set up A, decreased.
iv) Using your biological knowledge, indicate how results will change, if a fan is switched on near the experimental set up. Explain your answer.
