Reena took some moong seeds and soaked them overnight in water. Next day, after draining out the water, she wrapped the seeds in a wet cloth. After one day, she observed a small white structures growing out of the seeds. These small white structures will develop into
(A) Stems (B) Leaves (C) Roots (D) Flowers
The correct answer is: (C) Roots
Explanation:
When Reena soaks moong seeds in water, the seed absorbs water and swells up. The seed coat ruptures and the embryo emerges out. The radicle is the embryonic root of the plant that grows downward into the soil and forms a root.
