Which organelle of the leaf reflects back excess light?

The correct answer to this question is a wavy cuticle. The wavy cuticle helps plants keep up with the demands of the environment and can be found covering the leaves on all plants. It does so by providing barriers to keep some things in and out.

.The wavy cuticle also helps keep plants health, which allows the plants to group and function properly. It has many advantages, which include reducing water loss by sealing in the water. This makes the plant waterproof. The wavy cuticle also protects against heat, by keeping the plants cooler. They do so by reflecting the heat.
