Solution:

Fusiform root is a tap root modification. The root is swollen like a spindle being thickest in the middle and narrowing towards both apex and base, eg, Radish. In Indian radish only the base is formed of swollen hypocotyl.
When the adventitious roots singly become fleshy and tuberous as a result of food storage and do not assume any definite shape, they are called tuberous or single root tubers , Ipomoea batatas (Sweet potato).
Conical root is fleshy root like a cone, being thickest towards the base and gradually tapering towards apex, eg, carrot.
Napiform root is like a "top" or sphere that thins out abruptly at the apex. In turnip, the swollen part is hypocotyl. In beet, the swollen part is formed jointly by hypocotyl and tap root.
