2. Justify the following statements on the basis of external features:
     (i) Underground parts of a plant are not always roots.

Answers (1)

The roots of a plant are generally underground while the stem is present above the ground. However, the root doesn't need to be the only part of the plant to be found underground. In some specific conditions, stems are also found to be present in underground regions. For example, The stems in ginger and banana are underground and swollen due to the storage of food. They are called rhizomes. Similarly, the corm is an underground stem in Colocasia. Similarly, in peanuts, the flower after fertilization gets pushed inside the soil by growing a flower stalk. Hence, by this information, we can conclude that underground parts of a plant are not always roots.
