Question

Match List-I with List-II
\[\begin{array}{|l|l|} \hline \textbf{List-I} & \textbf{List-II} \\ \hline \text{(A). Autogamy} & \text{(I). Oxalis} \\ \hline \text{(B). Cliestogamy} & \text{(II). Garden pea} \\ \hline \text{(C). Dichogamy} & \text{(III). Date palm} \\ \hline \text{(D). Allogamy} & \text{(IV). Avocado} \\ \hline \end{array}\]
Choose the correct answer from the options given below:

• (A) - (IV), (B) - (II), (C) - (III), (D) - (I)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

For pollination mechanisms, associate key terms with examples: Cleistogamy = closed flowers (Oxalis, Viola), Dichogamy = different maturation times (Avocado, Walnut), Dioecy (requires Allogamy) = separate male/female plants (Date Palm, Papaya).

Answer 1

The Correct Option is C

Step 1: Introduction:
This question assesses your understanding of pollination mechanisms and their corresponding plant examples.

Step 2: Matching the Terms:
Match each term in List-I with its correct example from List-II:
\[\begin{array}{rl} \bullet & \text{(A) Autogamy: Self-pollination. The (II) Garden pea exemplifies autogamy due to its flower structure. } \\ \bullet & \text{(B) Cleistogamy: Self-pollination within unopened flowers. (I) Oxalis produces both closed, self-pollinating (cleistogamous) flowers and normal open flowers. } \\ \bullet & \text{(C) Dichogamy: Cross-pollination promoted by asynchronous maturation of male and female parts. (IV) Avocado exhibits synchronized dichogamy, functioning as female one day and male the next. } \\ \bullet & \text{(D) Allogamy: Cross-pollination between different plants. The (III) Date palm is dioecious, necessitating cross-pollination (allogamy) for fruit production. } \\ \end{array}\]The correct matching: A \(\rightarrow\) II, B \(\rightarrow\) I, C \(\rightarrow\) IV, D \(\rightarrow\) III.

Step 3: Answer:
The correct combination is in option 3.
