Question

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

Answer 1

Plants need this waxy outer coating, also known as a cuticle, for a variety of reasons. The cuticle keeps the important things the plant needs in, such as water and carbon dioxide, and the things the plant doesn't need, such as too much heat, out. It performs a few different functions, including protecting the important cells needed for photosynthesis.
