Compare wind-pollinated and insect-pollinated flowers. Give an example of each.
How to lay out the answer. Follow the frame, then write it in your own words.
1 · Define pollination in one line. Pollination is the transfer of pollen grains from the anther to the stigma of a flower.
2 · Wind-pollinated flowers. Light, non-sticky pollen made in large amounts; well-exposed stamens; large feathery stigma; small, dull flowers without nectar; for example maize and grasses.
3 · Insect-pollinated flowers. Large, colourful, fragrant flowers rich in nectar, or small flowers in a showy inflorescence; sticky pollen; for example Salvia and sunflower.
4 · Link to daily life. Farmers keep bee boxes near mustard and sunflower fields to improve seed set.
5 · Close in one line. So the form of each flower matches the agent that carries its pollen.
Scoring tip: A 3-mark comparison needs three clear points of contrast, best set out as a two-column table, plus an example of each.
