Question

A slender, prostrate sub-aerial branch of the stem which creeps along the ground helping in vegetative reproduction is

• A. Offset
• B. Sucker
• C. Runner
• D. None of the above

Answer 1

The correct option is C Runner

Runner is a type of sub-aerial modification which arises as a lateral branch from the base of stem running along the surface of soil. It develops nodes and internodes and at each node forms roots below and leaves above. The separation of runner form parent plant gives rise to new plant.

A sucker is a lateral branch that travels along the ground for some distance and then grows underground and then a gain turning up producing new plant.

Offsets are short runners which are generally found in aquatic plants and are one internode long.

Thus, the correct answer is option C.
