Question: what are the main differences between oogenesis and spermatogenesis?
Answer: Process: The process of spermatogenesis and oogenesis is different where one produces 'Sperms' from a 'Spermatogonium' and the other produces 'Ovum' from an 'Oogonium'. Occurrence: Spermatogenesis occurs inside the seminiferous tubules of a testis whereas oogenesis occurs inside the ovary.
