Question

Which of the following statements are correct? \[ \begin{aligned} I. &\text{Inflorescence in Carrot is Umbel}\\ II. &\text{Male flowers of Ficus have three stamens}\\ III. &\text{Pneumatophores of Rhizophora are positively geotropic}\\ IV. &\text{Axillary bud develops into tendril in Grapevine} \end{aligned} \] The correct answer is (and = all, only = only)

• A. I and II only
• B. II and III only
• C. III and IV only
• D. II and IV only

Hint:

Remember: \[ \boxed{ \begin{aligned} &\text{Carrot} &&\rightarrow \text{Umbel inflorescence} &\textit{Ficus} &&\rightarrow \text{Male flowers with 3 stamens} &\text{Pneumatophores} &&\rightarrow \text{Negatively geotropic} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Examine each statement. Statement I is correct. Carrot belongs to the family Apiaceae, in which the inflorescence is \[ \boxed{\text{Umbel}.} \] Statement II is correct. The male flowers of Ficus possess \[ \boxed{\text{three stamens}.} \] Statement III is incorrect. Pneumatophores of mangrove plants such as Rhizophora are \[ \boxed{\text{negatively geotropic}} \] as they grow upward for gaseous exchange. Statement IV is incorrect. In grapevine, the stem gives rise to tendrils opposite the leaves. The axillary bud normally develops into a branch and not into a tendril.

Step 2: Choose the correct statements. Hence, \[ \boxed{\text{Statements I and II only are correct}.} \] Therefore, the correct option is \[ \boxed{(A).} \]
