Question

The chief pollinators of our agri horticultural crops are _____
A. Moths
B. Bees
C. Beetles
D. Butterflies

Answer 1

Hint:
Pollen grains are the male gametophyte of the flowering plants. Pollination occurs when pollen grains are transferred to the stigma, a female part of the flowering plant from the anther that helps in fertilization.

Complete step by step answer:
Succeeding pollination the pollen grains are attached to the stigma, the style allows their migration to the ovary where the female and male gametophytes allow fertilization of the ovules and causes embryo development which further causes seed development and then a sapling.
Pollination can be either self-pollination or cross-pollination. Cross-pollination or allogamy is the pollination or transfer of the pollen grains from the stamen of one flower to the stigma of another flower of the same species and self- pollination occurs when the pollen of the flower pollinates to its own flower and mostly occurs when flowers are closed. Self-pollination can be autogamy or geitonogamy where the pollen of the flower gets pollinated to the stigma of the same flower or if it pollinates the stigma of other flowers of the same plant respectively.
There are two methods of pollination: biotic and abiotic methods. , In the abiotic method wind or water are the pollinating agents and in the biotic method insects, butterflies, honeybees and several birds are the pollinators. Bees are the most effective pollinators which spent most of their lifetime collecting pollen to feed their offspring and thus at some places honey bees and other species of bees are raised to fulfill this motto.
Hence, the correct option is (B).

Note:
The pollination through water is called hydrophily, and through wind is called anemophily whereas pollination by insects is called entomophily, by birds is called ornithophily. The natural pollinators are raised as they improve the quality and quantity of the crops and are financially beneficial.
