Question

Quizplus · Accepted Answer

The root apical meristem is covered by a protective cap called the root cap or calyptra. The root cap protects the meristem as it grows through the soil, and also secretes substances that lubricate the root and aid in its movement through the soil. Choice A is incorrect because root hairs are found on the mature, differentiated cells of the root, not on the root apical meristem. Choices C, D, and E are also incorrect because these layers are found deeper within the root and do not cover the apical meristem.
