BOTANY

Detailed explanation-1: -These flowers are generally larger in size. Pollination by animals is more efficient than wild pollination as many pollen get wasted during wind pollination. Thus, the correct answer is option (A).

Detailed explanation-2: -Angiosperms have several adaptations that make them successful on land including smaller, lighter pollen grains that can be easily distributed by the wind. They also have stamen to produce pollen and small female reproductive structures that allow them to quickly produce lots of seeds.

Detailed explanation-3: -Over millions of years, flowers have developed scents, colors, markings and shapes to attract certain pollinators, and certain pollinators have developed characteristics such as long tongues or beaks that enable them to reach the nectar in differently shaped flowers.

Detailed explanation-4: -The function of the flower is to ensure pollination. Flowers also provide protection for the ovule and developing embryo inside a receptacle. The function of the fruit is seed dispersal. They also protect the developing seed.

Detailed explanation-5: -Common insect pollinators include bees, wasps, flies, beetles, butterflies, and moths. Insect pollination in seed plants likely appeared in the Paleozoic. Entomophily has been documented in cycads and some gnetophytes among living gymnosperms.
