WebMar 26, 2024 · It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing. WebThe sperm's target is the egg. Since it is so much bigger than sperm, the egg is the source of cytosol and organelles, particularly mitochondria, for the future zygote. Unlike sperm, …
WebApr 23, 2024 · The key difference between somatic cell and egg cell is that somatic cell is a diploid cell that has a total of 46 chromosomes while egg cell is a haploid cell that contains 23 chromosomes. Cell is the smallest unit of the life. Hence, it is the building block of living organisms. There are different types of cells in a living organism. WebOne sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm, which serves as a source of nutrition for the developing embryo. Together, these two fertilization events in angiosperms are known as double fertilization, illustrated below.
