Final answer:
The end product of egg formation in humans is a large, nutrient-rich ovum or egg cell. This cell contains a haploid nucleus and substantial cytoplasm, making it much larger than sperm and providing nourishment to the embryo after fertilization.
Step-by-step explanation:
The end product of egg formation in humans is a large, nutrient-rich ovum. Human eggs, also known as ova, are among the largest cells in the human female body, being roughly 30 times wider than sperm cells. Each egg contains a haploid nucleus with half the usual number of chromosomes, as well as a substantial amount of cytoplasm, which contributes to its size. Unlike sperm, eggs do not have tails and contain substantial amounts of yolk, which provides nourishment to the developing embryo after fertilization. During fertilization, a sperm cell unites with the egg to form a diploid zygote, and the nourishment from the egg supports the embryo's initial growth.
Egg cells are known as female gametes and form in the ovaries. Even though a female is born with all her egg cells, these are not fully developed until puberty. Eggs are released from the ovaries into the fallopian tubes, where they can be fertilized by sperm. In some vertebrates, the yolk serves as a significant food source for the developing embryo, a role similar to that of the endosperm in plant seeds, which nourishes the growing plant embryo.
