Question

How does dermal tissue help 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 use water more quickly.

Answer 1

It has a waxy material that prevents the loss of water to the environment.

The dermal tissue (epidermis) produces a waxy cuticle that reduces water loss by evaporation. (Guard cells are also part of dermal tissue but they close, not open, on hot days to reduce water loss.)
