Detailed explanation-1: -When new cells are created in the apical meristem of the root they are small and rounded. In this region they grow in size, lengthening the root as they grow.

Detailed explanation-2: -The cells that are formed increase in length and thereby increase the length of the root. The area where these cells are formed is called the zone of elongation. Just above the elongation region lies the maturation region, where cells differentiate into various types of primary tissues.

Detailed explanation-3: -The elongation zone is near this root area. It is a region in all plant roots where cells are created and differentiate into several cell types. This zone is also known as the root-hair zone or differentiation zone. The cells in the elongation zone eventually mature and differentiate.

Detailed explanation-4: -The zone of elongation is where the newly-formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells differentiate into specialized cell types.

Detailed explanation-5: -Root hairs are found only in the zone of maturation, also called the zone of differentiation. They are not found in the zone of elongation, possibly because older root hairs are sheared off as the root elongates and moves through the soil.
