Question

Root hairs, stomata, are the organs that develops from ___________ tissue.

• A. Vascular tissue
• B. Meristematic tissue
• C. Epidermal tissue
• D. Medullary ray

Answer 1

The correct option is C Epidermal tissue

Epidermis:
The epidermis is usually made of a single layer of cells.

• The entire surface of a plant has this outer covering of epidermis.
• It protects all the parts of the plant.
• Epidermal cells on the aerial parts of the plant often secrete a waxy, water-resistant layer on their outer surface.
• This aids in protection against loss of water, mechanical injury and invasion by parasitic fungi.
• We can observe small pores here and there in the epidermis of the leaf. These pores are called stomata. They are necessary for exchanging gases with the atmosphere. Transpiration (loss of water in the form of water vapour) also takes place through stomata
• Epidermal cells of the roots, whose function is water absorption, commonly bear long hair-like parts called root hairs, that greatly increase the total absorptive surface area.
