NEETBotanySexual Reproduction in Flowering Plants
A botanist observes a plant species in which the flowers possess a single ovule in each ovary and are packed into a dense inflorescence. Based on these structural features, which of the following sets of floral adaptations is this plant most likely to exhibit?
Options
- ABrightly coloured petals and sticky pollen grains
- BRibbon-like pollen grains protected by a mucilaginous covering
- CWell-exposed stamens and large feathery stigmas
- DLarge feathery stigmas and abundant nectar production
Correct answer
C. Well-exposed stamens and large feathery stigmas
Step-by-step solution
The presence of a single ovule in each ovary and flowers packed into an inflorescence are characteristic features of wind-pollinated plants. Wind-pollinated flowers also possess well-exposed stamens so that the pollens are easily dispersed into wind currents, and large, often feathery stigmas to easily trap air-borne pollen grains. They produce light and non-sticky pollen. They do not produce brightly coloured petals or nectar, as these are adaptations to attract animal pollinators. Ribbon-like pollen with a mucila
