Answer: (D) (d) Wind pollinated plant inflorescence showing flowers with well exposed stamens.. Answer: D.
- A.(a) Water pollinated flowers showing stamens with mucilaginous covering.
- B.(b) Cleistogamous flowers showing Endogamy.
- C.(c) Compact inflorescence showing complete autogamy
- D.(d) Wind pollinated plant inflorescence showing flowers with well exposed stamens.✓
Correct Answer
(D) (d) Wind pollinated plant inflorescence showing flowers with well exposed stamens.
Solution & Explanation
Answer: D. The figure shows a wind-pollinated plant inflorescence with well-exposed stamens. Wind-pollinated flowers possess well-exposed stamens so the light, non-sticky pollen is easily dispersed into wind currents, and they typically have numerous flowers packed into a compact inflorescence. This matches option (d); options describing mucilaginous water-pollination, cleistogamy/endogamy or complete autogamy do not fit. NCERT: Ch 1, p.13, lines 6-15 — "Wind pollination also requires that the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens... and large often-feathery stigma to easily trap air-borne pollen grains. Wind-pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence."
