The difference between spermiogenesis and spermiation is
- In spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed.
- In spermiogenesis spermatozoa from sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed.
- In spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed.
- In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.
The Correct Option is D
Solution and Explanation
Spermatogenesis is the process of sperm cell development, and it can be divided into different stages, including spermiogenesis and spermiation. Understanding each of these stages is crucial for differentiating between them.
-
Spermiogenesis: This is the process where the spermatids, which are formed after meiotic division, transform into spermatozoa (mature sperm cells). During spermiogenesis, several changes occur:
- Condensation of nuclear chromatin to form a compact and hydrodynamically efficient nucleus.
- Development of the acrosome from the Golgi apparatus, which is essential for the sperm to penetrate the oocyte (egg cell).
- Formation of the flagellum for motility.
- Shedding of excess cytoplasm as residual bodies.
- Spermiation: This step follows spermiogenesis. In spermiation, the mature spermatozoa are released from the Sertoli cells into the lumen of the seminiferous tubules, from where they are transported through the male reproductive tract. Essentially, spermiation is the release phase where the spermatozoa become free-swimming entities.
The key difference lies in what occurs during each process:
- In spermiogenesis, spermatids are transformed into fully developed spermatozoa.
- In spermiation, these spermatozoa are released from the Sertoli cells into the cavity of the seminiferous tubules to continue their journey through the male reproductive tract.
Therefore, the correct answer is: In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.
