Question 34 • 26-27 - C - RUSD Biology in the Living Earth

What would most likely happen to plants if they did not have a waxy outer coating?

Answer
A
They would photosynthesize at a faster rate.
B
They would store more water in their leaves.
C
They would store more sugars in their leaves.
D
They would be harmed by insects and UV radiation.

Explanation

The waxy outer coating, or cuticle, helps protect a plant’s surface and reduces water loss. Without it, plants would be more vulnerable to environmental damage, including UV radiation and some pests. They would not photosynthesize faster or store more water or sugar as a result of losing the coating, so D is correct.
