Fertilisation is the process by which a sperm cell fuses with an egg cell to form a zygote, which later develops into an embryo. It is a crucial step in sexual reproduction, where two gametes (sperm and egg) combine their genetic material to create a new individual with a unique set of genes. Fertilisation typically takes place internally in most animals, while in plants, it can occur through pollination and the transfer of pollen grains to the ovules.
Fertilization is the process by which a sperm cell and an egg cell fuse, resulting in the formation of a zygote. This process occurs in sexual reproduction, where male and female gametes combine to initiate the development of a new individual. Fertilization typically occurs in the reproductive organs of plants and animals, such as the ovary in animals and the ovule in plants. The sperm cell must first reach the vicinity of the egg cell, either by external or internal fertilization, depending on the organism. Once the sperm reaches the egg, it penetrates the egg's protective layer and fuses with the egg's nucleus. This fusion combines the genetic material from both the sperm and the egg to form a unique set of chromosomes in the zygote. As a result, fertilization is a crucial event that marks the beginning of the development of a new organism.
