Correct Answer
(B) (b) To trap pollen grains
Solution & Explanation
Answer: B. The corn cob is the classic wind-pollinated example: the silky tassels (ears) seen on it are nothing but the stigma and style which wave in the wind to trap the light, air-borne pollen grains. Their function is therefore to trap pollen grains. NCERT: Ch 1, p.13, lines 12-19 — "a familiar example is the corn cob – the ears you see are nothing but the stigma and style which wave in the wind to trap pollen grains. Wind-pollination is quite common in grasses."
