Question

All the following plants have flowers producing assured seed set even in the absence of pollinators, except

Answer 1

Solution

Plants like Oxalis, Viola, and Commelina exhibit cleistogamy, where flowers remain closed and self-pollinate, ensuring seed set without pollinators. Yucca has an obligate mutualism with the Yucca moth for pollination; without the moth, seed set does not occur.
