In flowering plants, which process refers to the fertilization of the ovum by the sperm cell?

The chosen answer is accurate because fertilization specifically refers to the union of an ovum and a sperm cell, resulting in the formation of a zygote. In flowering plants, this process occurs when a sperm cell from pollen successfully reaches and penetrates the ovule within the ovary of a flower. This union is essential for sexual reproduction in plants, leading to the development of seeds.

Germination pertains to the process where a seed develops into a new plant, which occurs after fertilization and seed formation. Pollination is the transfer of pollen grains from the male anther to the female stigma of a flower, which is a preliminary step leading to fertilization but does not encompass the actual fusion of gametes. Oogenesis refers to the development of female gametes or ova within the ovary, rather than the fertilization process itself. Each of these terms describes different aspects of plant reproduction, yet fertilization remains the critical act of sperm meeting ovum.
