PLANT REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some plants have evolved to use less energy on producing large showy flowers, yet they are still successful at reproducing sexually. These plants are most likely pollinated by
A
animals that can see different wavelengths of light.
B
small insects that have a very keen sense of smell.
C
the wind dispersing their pollen large distances.
D
self-pollination methods.
Explanation: 

Detailed explanation-1: -In mutualistic relationships between flowers and their pollinators, flowers benefit by having their pollen efficiently distributed to other flowers of the same species, allowing them to reproduce. Pollinators benefit by feeding on the nutritious pollen and nectar that flowers provide.

Detailed explanation-2: -Two strategies evolved to prevent self-pollination are pollen release time and hypogynous flower.

Detailed explanation-3: -Unlike the typical insect-pollinated flowers, flowers adapted to pollination by wind do not produce nectar or scent. In wind-pollinated species, the microsporangia hang out of the flower, and, as the wind blows, the lightweight pollen is carried with it.

Detailed explanation-4: -Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago. Angiosperms have developed flowers and fruit as ways to attract pollinators and protect their seeds, respectively. Flowers have a wide array of colors, shapes, and smells, all of which are for the purpose of attracting pollinators.
