Question

Oxalis and Commelina produce which two types of flowers? Name them.

Hint:

Chasmogamous = open flowers (cross/self-pollination). Cleistogamous = closed flowers (only self-pollination).

Answer 1

Oxalis and Commelina exhibit two types of flowers: \begin{enumerate} \item Chasmogamous flowers: - These are open flowers with exposed anthers and stigma. - They allow cross-pollination as well as self-pollination. \item Cleistogamous flowers: - These are closed flowers where anthers and stigma remain enclosed. - They ensure obligate self-pollination and guarantee seed formation even in the absence of pollinating agents. \end{enumerate} Conclusion: By producing both chasmogamous and cleistogamous flowers, plants like Oxalis and Commelina ensure reproductive assurance under different environmental conditions.
