Which of the following event in the reproduction in flowering plants can be carried out by a butterfly?
(a) Germination
(b) Fertilisation
(c) Pollination
(d) Seed formation
Correct Answer: (c) Pollination
Explanations:
Butterfly helps in the pollination process where pollen grains are transferred from the male anther of a flower to the female stigma, for the fertilization and production of seeds. Pollen grains are stuck on the body parts of the butterfly and transferred to other flowers where it sits back to suck nectar.
Different types of pollination are self-pollination and cross-pollination.
Self-Pollination - This types of pollination occur when the pollen of one flower transfers to the stigma of the same flower, or another flower of the same plant.
Cross-Pollination - This types of pollination occurs when the pollen of one flower transfers to the stigma of another flower of different plants of the same species.
Pollination is done either by biotic agents like insects, birds, and bats or by abiotic agents like wind and water.
Pollination is the transfer of male gametes onto the female gametes, while fertilization is the fusion of these two gametes. It is the process in which the nuclei of the female gamete and male gamete unite together in the ovary of the flower to form a diploid zygote.
