Question

Lateral roots are

• A. stelar in origin
• B. cortical in origin
• C. stelar and endogenous in origin
• D. cortical and exogenous in origin

Answer 1

The correct option is C stelar and endogenous in origin

Lateral roots arise from the pericycle. Pericycle is a part of stelar region in plants. Stelar region includes pericycle, vascular bundles and pith. As lateral roots grow through the cortex and epidermis, they are said to be endogenous in origin. Hence, lateral roots are stelar and endogenous in origin.
