- DA - Napiform, carrot; b - Nodulated, Tamarind; C - Tuberous, turmeric
Correct answer
C. A - Conical, carrot; B - Tuberous, sweet potato; C - Fasciculated, Dahlia
Step-by-step solution
Conical roots are conical in shape (widest at the top, tapering smoothly towards the bottom), e.g., carrot (Daucuscarota). Tuberous roots become fleshy and tuberous as a result of food storage, e.g., sweet potato (Ipomoea batata). Fasciculated roots are produced from one place forming a tuft or cluster. In Dahlia, the clusters of modified adventitious roots are formed at the base of the stem.
