Question

In which parts of the plants of Dioscorea and Agave, the food material is stored?

\[ \begin{array}{|c|l|l|} \hline & \textit{Dioscorea} & \textit{Agave} \\ \hline \text{I} & \text{Floral buds} & \text{Tap root} \\ \hline \text{II} & \text{Subaerial stem} & \text{Floral buds} \\ \hline \text{III} & \text{Underground stem} & \text{Vegetative buds} \\ \hline \text{IV} & \text{Vegetative buds} & \text{Floral buds} \\ \hline \end{array} \]

• A. I
• B. III
• C. II
• D. IV

Hint:

Remember the examples of vegetative propagation: \[ \boxed{ \begin{aligned} &\textit{Dioscorea} &&\rightarrow \text{Vegetative buds (bulbils)} &\textit{Agave} &&\rightarrow \text{Floral buds (bulbils)} \end{aligned} } \]

Answer 1

The Correct Option is D

Step 1: Recall the storage organs. In Dioscorea (yam), food is stored in \[ \boxed{\text{vegetative buds (bulbils).}} \] In Agave, food is stored in \[ \boxed{\text{floral buds (bulbils).}} \]

Step 2: Identify the correct combination. Thus, the correct combination is \[ \boxed{ \text{Dioscorea} \rightarrow \text{Vegetative buds},\qquad \text{Agave} \rightarrow \text{Floral buds}. } \]

Step 3: Choose the correct option. Hence, the correct option is \[ \boxed{(D).} \]
