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: -Statement 1: Root cap protects the root meristem from the friction of the soil and its outer cells are continuously replaced by newer ones. Statement 2: The effect of the soil-friction damages the outer cells of root cap which are peeled off and replaced by new cells produced by root meristem.

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 root cap, a small tissue at the tip of the root, protects the root from environmental stress and functions in gravity perception. To perform its functions, the position and size of the root cap remains stable throughout root growth.

Detailed explanation-5: -The root cap is the root’s outermost tip. It consists of cells that are sloughed off as the root grows through the soil. Its function is to protect the root meristem.
