What Are The Characteristics Of Insect-pollinated Flowers And Wind-pollinated Flowers?


Answer:
First let us list the characteristics of insect-pollinated flowers:
1.Flowers are usually large, brightly-colored and stinking to attract insects. If the flowers are small they may group together to form conspicuous inflorescences.
2.Nectar is often present to attract insects.
3.Pollen is fairly abundant. Pollen grain are large sticky and heavy, usually with rough surfaces so that they can readily cling onto the insects bodies.
4.Stamens may not be pendulous.
5.Stigmas are usually not downy and do no protrude. They are sticky so that pollen grains settling on them are not easily displaced.
6.Nectar guides may be seen on the petals.

Now coming to the characteristics of wind-pollinated flowers:
1.Flowers are usually small, dull-colored and scentless and thus not attractive to insects.
2.Nectar is usually mislaid.
3.Pollen is abundant as wastage is higher. Pollen grains are small, dry, smooth and bedside light so that they are buoyant and easily blown about by air currents.
4.Stamens usually own long, slender filaments that sway in the slightest wind and pollen grain are hence shaken out from the anthers.
5.Stigmas protrude and are large and feathery so that they provide a large surface nouns to catch pollen floating in the air.
6.Nectar guides are away.
