When a bee helps pollinate flowers, it is assisting in
A
asexual reproduction
B
sexual reproduction
C
vegetative propogation
D
fragmentation
Explanation: 

Detailed explanation-1: -Pollination is the main mode of sexual reproduction in plants, which occurs when the transfer of pollen (male) from the anther of a flower to a stigma (female) results in fertilization which produces seeds and, in some cases, fruits.

Detailed explanation-2: -Pollination is sexual reproduction, plant style. Plants can’t move – much – so most of them need pollinators to help them reproduce (unless they’re wind pollinated, like grasses). Insect pollinators feed on the flower’s pollen or the nectar it produces, or both.

Detailed explanation-3: -Bees are essential in growing flowers and plants. They use the process of pollination where they transfer tiny little grains of pollen from the flower of one plant to the flower of another of the same kind of plant. Transferring this pollen helps the flowers to continue to grow.

Detailed explanation-4: -Pollen, which contains a lot of protein and is primarily used to rear the brood, is picked up by the bees almost as they fly past. It sticks to the hairs on the bees, and when they visit the next plant of the same species it is transferred in adequate quantities to their stigma.

Detailed explanation-5: -Pollen, looking like insignificant yellow dust, bears a plant’s male sex cells and is a vital link in the reproductive cycle. With adequate pollination, wildflowers: Reproduce and produce enough seeds for dispersal and propagation. Maintain genetic diversity within a population.
