Question

Supporting roots of sugarcane arise from:

• A. lower nodes of stem
• B. radicle
• C. aerial branches of stem
• D. internodes of stem

Answer 1

The correct option is A

lower nodes of stem

• Two types of roots have been observed in plants like sugarcane, sorghum, maize, etc., one which grows beneath the soil and the other growing from the stem just above the soil. Such roots are called adventitious roots.
• They are modified for additional functions like respiration, storage, support, etc.
• In sugarcane the roots that arise from the lower nodes of the stem are called stilt roots for the support of plant.
