- 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 39.9 0.8 B 38.7 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.What is pericarp?Label all the visible parts of this stem cross section of gumamela. Also, provide an appropriate description for this image.

Label the following structures: A.) thallus, B.) gemma cup, C.) gemmae.Compare the leaf structure of Nerium to Ligustrum. Look for stomata. Where are they located? On the upper or lower leaf surface? How is the surface of the leaf modified? Can you recognize why these leaves are said to have “sunken stomata”? Look for “hairs” on the leaf surface. Where are they located? How are they advantageous? How does the appearance of each tissue layer in Nerium differ from Ligustrum? Compare the upper epidermis to the lower epidermis. Compare the amount of cuticle.
