उत्तर
| Sr. No. | Feature | Spermatogenesis | Spermiogenesis |
| 1. | Definition | It is the complete process of the formation of mature male gametes (spermatozoa) from diploid spermatogonia. | It is the final stage of spermatogenesis, where non-motile spermatids are transformed into motile spermatozoa. |
| 2. | Nature of Process | This process involves both mitotic and meiotic cell divisions to increase the cell count. | This process involves no cell division; it is only a structural metamorphosis or differentiation of cells. |
| 3. | Outcome | It starts with a single diploid cell and results in the formation of four haploid spermatids. | It results in the conversion of a round, heavy spermatid into an elongated, light, and functional sperm. |
| 4. | Key Changes | It involves stages of multiplication, growth, and maturation to form various intermediate cell types. | It involves specific changes like acrosome formation, nucleus condensation, and the development of a tail. |
