Question

Piliferous layer of root is actually
A. Pericycle
B. Endodermis
C. Conjunctive parenchyma
D. Epidermis

Answer 1

Hint: The internal structure of each part of the plant is different. The roots, stem and leaves contain different types of special cells which are able to perform particular functions. The epidermis is a solitary layer of cells that covers the leaves, flowers, roots and stems of plants externally. It forms a boundary between the plant and the outer climate.

Complete answer: Roots are frequently underground, however the root framework can be just as gigantic as the over-the-ground shoot system.
A functioning root system makes it feasible for the plant to complete development, photosynthesis and other compound responses, spreading, blooming, fruiting, and seed creation.
Roots are so basic to plant survival that a growing seedling dedicates its first days to root development previously permitting keeps to pop separate from the seed.
The ground tissue system carries parenchymatous cells as well as conjunctive parenchyma which constitute the cortex.
The endodermis is the first layer within the stele that lies after the cortex.
Pericycle is the layer of cells which are present inside the endodermis.
Piliferous layer is a locale of the epidermis of a root, a short distance from the tip, that produces abundant root hairs and is engaged with the take-up of water and supplements.
Epidermis with root hairs is named as piliferous layer or rhizodermis or epiblema. It is found in dicot root as well as in monocot root.
Piliferous layer is also called a root-hair zone.
Epidermis with root hairs is called Piliferous layer. So, the correct option is ‘D' i.e. Epidermis.

Note: Woody stems and some other stem structures such as potato tubers produce an optional covering called the periderm that replaces the epidermis as the defensive covering.
Epidermis is a part of the epidermal tissue system while Endodermis and Pericycle is a part of the ground tissue system.
