Please attempt this question first.
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. |

Which one of the following statements about human sperm is correct?
| 1. | The acrosome has a conical, pointed structure used for piercing and penetrating the egg, resulting in fertilization. |
| 2. | The sperm lysins in the acrosome dissolve the egg envelope, facilitating fertilization. |
| 3. | The acrosome serves as a sensory structure, leading the sperm towards the ovum. |
| 4. | The acrosome serves no particular function. |
