How does the process of fertilisation take place in flowers?

In flowers, fertilization occurs as pollen grains (carrying male gametes) land on the stigma. Pollen tubes grow from the stigma to the ovary, releasing sperm cells. One sperm fertilizes the egg cell in the ovule, forming the embryo, while another fertilizes two other nuclei, forming the endosperm. This union creates seeds within the ovary. Eventually, the ovary matures into a fruit, safeguarding the seeds. Fertilization in flowers leads to seed and fruit formation, enabling plant reproduction.
