Question

Radish is an example of
a) fusiform root
b) napiform root
c)conical root
d)tuberous root

Answer 1

Hint Radish is the underground root that stores the food material in it. It has a modified root in which the main root is swollen and the other secondary roots emerge from it. It has a tapering end and has a spindle-shaped structure.

Complete answer: The root of the radish is the modified root and is known as the fusiform root. This type of root has a tapering end part and the tapering top part. It forms a spindle-like shape. The middle part of the root is mostly swollen. And is used as a storage organ. The radish has a taproot. The secondary root hairs arise from the swollen part of the root.

Additional information:
-Napiform root modification can be seen in turnips. In this type of root, the root is swollen in such a way that it appears broader in structure than longer. It has small root hairs arising from the tapering end present below the swollen part.
-Conical root is mostly seen in the carrots. In this type of root form, the roots are conical in shape or we can say that the root is mode wider at the top and becomes narrow and tapering when moving towards the bottom of the root.
-Tuberous root is the modified storage organs. They have a shoot present at one end and root present at another end. They are usually found in the sweet potato.

So, the answer is ‘fusiform root’.

Note: The fusiform root, conical root, and napiform root are the modification of the taproot system. in the tap root system, there is one main primary root and from it, the secondary root arises. The primary root is connected to the stem of the plant.
