How does dermal tissue plants on a hot day? it releases substances so plants can absorb more water from the soil. it has a waxy material that prevents the loss of water to the environment. it has guard cells that open to prevent the loss of water to the environment. it contains chemical substances that allow plants to produce water.

Dermal tissue helps plants on a hot day due to the waxy coating it provides, that prevents to the loss of water to the environment. This waxy material that is produced is also known as the cuticle. There are guard cells within the epidermis, as mentioned in the question, but these are responsible for moderating gas exchange rather than specifically prevent water loss. Hope that answered your question.
