What is the primary function of flower petals? Would you expect a species that does wind pollination to have prominent petals? Why or why not?

A plant’s flowers have developed large, brightly-colored petals that are wide open during the day. Which statement describes how this plant is MOST likely pollinated?Select one:a.Nocturnal pollinators visit the plant at night when the closed petals keep the pollen on the flower. During the next day the pollen moves into the ovary.b.Hovering insects are attracted to the flower by its bright colors; pollen falls from their bodies as they fly over the petals.c.Wind-borne pollen from many other species of flowering plants is able to fall onto the stigma in the center of the petals; then it fertilizes the ovules.d.Bees easily see the flower and use the petals as a landing pad while they collect nectar, depositing pollen from other flowers of the same species.

Pollinating agentsThe pollen-pistil interaction begins with pollination, followed by pollen adhesion to the stigma.After it adheres, it imbibes water and gets hydrated which initiates pollen tube germination.There are different agents of pollination like wind, insects, birds and water.Anemophilous flowers are pollinated by the agency of wind. These flowers are small andinconspicuous.. The pollen grains are very light, non-sticky and sometimes winged.Entomophilic flowers are pollinated by insects. These flowers are often attractive to look at withbright petals and are fragrant to attract the insect visitors to them. They often have broadstigmas or anthers to allow the insect to perch on it. Many of the insect-pollinated flowers alsosecrete nectar which attracts bees, butterflies or other similar insects to the flowers. The pollengrain surface of such flowers produce mucilaginous secretion.Hydrophilic flowers are pollinated by water. It is commonly found in algae, bryophytes,pteridophytes and some angiosperms. The pollen grains may have a mucilaginous covering toprotect it from getting wet.i The pollinating agent of an inflorescence of small dull coloured flowers with well exposedstamens and large feathery stigma isa. Water b. Wind c. Insects d. Birds.ii An example of biotic agent for pollination isa. Air b. Water c. Honey bee d. All of the aboveiii The pollen grains in the flowers are generally sticky that help them toa. stick on to the body of the insects b. float on waterc. float in the air d. fall on the ground safely.iv Which of the following statements seem to describe the water-pollinated submerged plants?a. The flowers do not produce nectar.b. The flower petals are not brightly coloured.c. The pollen grains have mucilaginous covering.d. The female flowers have long stalk to reach the surface.ORAssertion: The pollen grains are easily carried by the wind.Reason: They are very light and sometimes winged.a. Both assertion and reason are true, and the reason is the correct explanation of the assertion.b. Both assertion and reason are true, but the reason is not the correct explanation of theassertion .c. Assertion is true but the reason is false.d. Both assertion and reason are false
