WebSperm are ejaculated in semen, a basic fluid with a pH of about 7.4. The 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, the egg has not completed meiosis - it’s stuck in the Metaphase II stage of division. WebSexual reproduction uses the process of meiosis, which creates gametes.
