Question

Which one of the following is a fruit?
A. Ginger
B. Sweet potato
C. Radish
D. Ladyfinger

Answer 1

Hint:
Fruit is a ‘mature’ or ripened ovary with contents of an ovary inside it, like seed(s). The seeds are also a mature form of the ovules which are enclosed by the ovary. Fruit can contain either one or more than one seeds.

Complete answer:
Ginger is an underground stem that lies parallel to the round. It grows in tropical conditions. It is used as a spice or for medicinal purposes. It is technically referred to as a rhizome as it stores starch and other nutrients to survive in unfavourable conditions and shoot as well as root contents can propagate through it.
Sweet Potato or Ipomea batatas is an adventitious root, also known as root tuber. Such roots store food and water. It is fusiform in shape, that is, it tapers on both ends but is thick in the middle.
Radish, too, is a root. Precisely, it is a taproot, that is to say, it grows as a primary root which offsets secondary roots.
Ladyfinger develops from a mature ovary and has multiple seeds inside. Therefore, it can be attributed to being a fruit.
Thus, the correct answer is:Ladyfinger

Option ‘D’ is correct

Note:
For a part of the plant to be a stem, it must have nodes and internodes. Therefore, a potato is a stem while a sweet potato is a root.
Rhizomes are underground stems usually found placed laterally. These help in the storage of food and produce shoot and root components just like any other stem.
