Question

Choose the correct statement from the following

• A. Cleistogamous flowers always exhibit autogamy
• B. Chasmogamous flowers always exhibit geitonogamy
• C. Cleistogamous flowers exhibit both autogamy and geitonogamy
• D. Chasmogamous flowers never exhibit autogamy

Hint:

\[ \boxed{ \begin{aligned} &\text{Cleistogamous flowers} &&\rightarrow \text{Always autogamy} &\text{Chasmogamous flowers} &&\rightarrow \text{May show autogamy, geitonogamy or xenogamy} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Recall cleistogamous flowers. Cleistogamous flowers never open. Hence, pollination occurs within the same flower. Therefore, \[ \boxed{\text{Cleistogamous flowers always show autogamy}.} \]

Step 2: Examine the remaining statements. Chasmogamous flowers may undergo autogamy, geitonogamy or xenogamy depending on the pollinating agent. Hence, statements (B), (C) and (D) are incorrect.

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