The difference between spermiogenesis and spermiation is?
1. In spermiogenesis, spermatids are formed, while in spermiation, spermatozoa are formed.
2. In spermiogenesis, spermatozoa are formed, while in spermiation, spermatids are formed.
3. In spermiogenesis, spermatozoa from Sertoli cells are released into the cavity of seminiferous tubules, while in spermiation, spermatozoa are formed.
4. In spermiogenesis, spermatozoa are formed, while in spermiation, spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules.
