Which of the statements below is not characteristic of wind-pollinated flowers?

A. Stigmas are usually large and feathery

B. Nectary is usually absent

C. The pollen grains have rough spiny surfaces

D. The flowers are not scented

QUICK ANSWER…

C

DETAILS…

Rough spiny surfaces aren’t known as one of the properties of wind-pollinated flowers.

Wind pollinated flowers must have pollen grains and stigmas that support easy and efficient transfer during pollination.

Now for the right answer to the above question:

1. Option A is incorrect. Stigmas are truly usually large and feathery.
2. Option B is incorrect. Yes, nectary is usually absent.
3. C is correct. spiny surfaces are not part of the characteristics.
4. D is not the correct answer. The scent is only required for insect, or animal pollinated flowers.

KEY-POINTS…
