Why is root hair a cells?

Answer 1

the root hair cell has a thin wall so water can pass through it easily

Answer 2

root hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are invisible to the naked eye. They are found only in the region of maturation of the root. Just prior to the root hair cell development, there is a point of elevated phosphorylase activity

Answer 3

because;

• it is thin because it means that it can absorb water much more efficiently and productively.

• it is long so that more of the surface area touches the soil (or environment of living) meaning that it has more chance of finding water and nutrients.
