A) Root cap
B) Meristematic zone
C) Root hairs
D) Root apex
Correct Answer: C
Solution :Root hairs are tiny, hair-like outgrowth of some surface cells of plant roots that greatly increases the area available for the absorption of water and other materials such as minerals. It is a delicate structure, which survives for a few days only and does not develop into a root. Root hair cells are found just behind the root tip where they are continually being formed. They grow out into the soil for a few millimetres to produce the root hair. Each root hair is made of a single cell. At the root tip mitosis cell division is very active making new cells for growth to replace the root hair cells that die.
