The layer that covers the apical meristem of a root is called the
A
pericycle
B
taproot
C
root cap
D
root hair
Explanation: 

Detailed explanation-1: -The root apical meristem, or root apex, is a small region at the tip of a root in which all cells are capable of repeated division and from which all primary root tissues are derived. The root apical meristem is protected as it passes through the soil by an outer region of living parenchyma cells called the root cap.

Detailed explanation-2: -The root apical meristem (RAM) is the region within the root tip from which all primary root tissues and the root cap are derived. The RAM consists of many cells that are actively engaged in division, growth and differentiation.

Detailed explanation-3: -The small tissues present at the tip of the root of the plant is known as root cap. The root cap is also known as calyptra.

Detailed explanation-4: -The very tip of the root is covered by a thimble-shaped root cap, which serves to protect the growing tip as it makes its way through the soil. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells.

Detailed explanation-5: -Caliptra or root cap surrounds the root apical meristem and protects it against potential ground abrasion during the root growth. Root cap is made up of parenchymatic cells that release substances containing glycosominoglycans, which work as lubricants.
