Question

Name the following.

The structure through which thin, delicate root hairs extend.

Answer 1

Epidermis:

1. The thin, delicate root hairs extend from the epidermis of the root.
2. The epidermis is the outermost cellular layer of the root composed of thin-walled parenchymatous cells.

Root hairs:

1. The root hairs are simply protoplast outgrowths that extend into the soil. They have very thin walls and are highly fragile.
2. They increase the surface area of epidermal cells to increase the mineral absorption process.

So, the structure through which thin, delicate root hairs extend is the epidermis.
