How to draw internal structure of

ABOUT DIAGRAM: The internal structure of a monocot root like maize, rice, wheat etc. can be described as follows; 1. Epidermis: The epidermis or outermost layer of the root is known as rhizodermis. It is composed of compact parenchymatous cells having no intercellular spaces. Root hairs in epidermis absorb water and minerals salt. 2. Cortex: The cortex lies below the epidermis consisting of thin walled parenchymatous cell having intercellular spaces. It help in conduction of water and minerals salts from root hairs to inner tissues and storage of food. 3. Endodermis: It is innermost layer of cortex which is composed of barrel shaped, compact cells having no intercellular spaces. Young endodermal cell have internal strip of suberin and lignin. Endodermis is to regulate flow of fluid both inward and outward. 4. Stele: It consists of pericycle and vascular tissues where pericycle lies just below the endodermis and composed single layered sclerenchymatous cells and in other side vascular tissues consists of alternating strands of xylem and phloem. The bundles are numerous and referred as polyarch. #Please Like, Comments, Share & Subscribe
