Which of these structure-function pairs is correct?

D)wax-makes leaf slippery so insects skid off
E)guard cells-prevent insects from laying eggs on leaves

Question

Quizplus · Accepted Answer

The cuticle is the waxy layer on the surface of leaves and it is responsible for inhibiting water loss and preventing pathogens from entering the plant. Stomata are small openings on the surface of leaves that allow for gas exchange, not protection against pathogens. Trichomes are small hairs on the surface of leaves that can secrete various compounds, but they are not responsible for the waxy cuticle. Wax is a component of the cuticle, but it does not make leaves slippery to prevent insect laying. Guard cells are the cells that regulate the opening and closing of stomata, they are not responsible for preventing insect laying.
