NEETBotanySexual Reproduction in Flowering Plants
In a corn cob, the familiar 'tassels' that are seen waving in the wind represent specific floral parts. Identify these parts and their primary biological function.
Options
- AAnther and filament; to disperse large quantities of pollen into the wind
- BStigma and style; to trap wind-borne pollen grains
- COvary and ovule; to remain exposed for direct reception of pollen grains
- DPetals and sepals; to provide aerodynamic support for pollen dispersal
Correct answer
B. Stigma and style; to trap wind-borne pollen grains
Step-by-step solution
According to NCERT, wind-pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence. A familiar example is the corn cob. The tassels seen on the corn cob are the stigma and style. Their function is to wave in the wind to act as a feathery net to trap wind-borne pollen grains. They are not the anther and filament (which would disperse pollen), nor are they petals and sepals (which are generally reduced or absent in wind-pollinated flowers since there is no need to at
