Oosite and spermatosite refer to the female and male gametes in the context of reproduction. An oosite, also known as an oocyte, is the female reproductive cell that develops into an ovum or egg after maturation. Conversely, a spermatosite, also referred to as a spermatocyte, is a male reproductive cell that undergoes meiosis to form sperm. Both are crucial for sexual reproduction, contributing genetic material to the offspring.
