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: -Individual bees tend to focus on one kind of flower at a time, which means it is more likely that pollen from one flower will be transferred to another flower of the same species by a particular bee. Many plants require this kind of pollen distribution, known as cross-pollination, in order to produce viable seeds.

Detailed explanation-3: -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-4: -Pollination is a very important part of the life cycle of a flowering plant. It is part of the sexual reproduction process of flowering plants, which results in seeds that will grow into new plants.

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.
