Question

Students were on an excursion to a botanical garden. They noted the following observation. Will you be able to help them in understanding those condition?

Many oblique roots were given out from the lower nodes, apparently for extra support.

Answer 1

1. Students must have observed adventitious roots in monocotyledonous plants like maize, sugarcane, wheat, etc.
2. Adventitious roots develop from any part of a plant other than the radicle.
3. In such plants, adventitious roots arise from the lower node of a stem and provide extra support to the plant. These roots are also called as stilt roots.
