Question

Lateral roots arise from the

• A. endodermis
• B. pericycle
• C. pith
• D. conjunctive tissue

Answer 1

The correct option is B pericycle

Lateral roots arise from the pericycle layer of the root. They extend horizontally from the primary root and increase the surface area of the root system. They help in better anchorage and absorption of water and minerals from the root.

The innermost layer of the cortex is called the endodermis which has a deposition of suberin along the radial and tangential walls in the form of casparian strips.

Pith is the central most region of roots and stems and is made up of parenchyma cells.

The parenchymatous cells present between xylem and phloem in the root is called conjunctive tissue.
