Question

The difference between spermiogenesis and spermiation is?

• A. In spermiogenesis, spermatozoa from Sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed
• B. in spermiogenesis, spermatozoa are formed, while in spermiation, spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules
• C. In spermiogenesis, spermatids are formed, while in spermiation, spermatozoa are formed
• D. In spermiogenesis, spermatozoa are formed, while in spermiation, spermatids are formed

Answer 1

The correct option is B

in spermiogenesis, spermatozoa are formed, while in spermiation, spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules

The correct option is B.

Explanation for Correct option:

1. Two processes take place as sperm develop: spermatogenesis and spermiogenesis.
2. The development of spermatids into spermatozoa or sperm cells is known as spermiogenesis.
3. Prior to moving on to the epididymis, mature sperm are discharged from Sertoli cells into the lumen of the seminiferous tubule by the process of spermiation.
4. Spermatids mature into mature, mobile, or motile spermatozoa during the final stage of spermatogenesis.
5. Before moving on to the epididymis during spermiation, mature spermatids are released from Sertoli cells into the lumen of the seminiferous tubule.

Explanation for Incorrect option:

Option A:

1. The process of producing sperm cells is known as spermatogenesis; the germ cells give rise to haploid spermatozoa.
2. The seminiferous tubules, a complex collection of tubes found inside the testes, are where sperm are produced.

Option C:

1. As a result, spermatids are naturally haploid and connected to one another by cytoplasmic bridges that have extra cytoplasm close to the nuclei.
2. Spermatogenesis is the formation and maturation of sperm cells within the testes and the male reproductive organs.
3. The seminiferous tubules, which make up the majority of the testes' tiny, tightly coiled tubules, are where sperm cells are created.
4. Spermatogenesis is the process by which spermatozoa are created from germ (stem) cells.
5. Proliferative, meiotic, and spermatogenic stages make up the process of spermatogenesis.
6. The mitotically active spermatogonia, or stem cells, are involved in the proliferative phase.

Option D:

1. Spermatogenesis is the process by which spermatozoa are created from germ (stem) cells.
2. Proliferative, meiotic, and spermatogenic stages make up the process of spermatogenesis.
3. The mitotically active spermatogonia, or stem cells, are involved in the proliferative phase.
4. As a result, spermatids are naturally haploid and connected to one another by cytoplasmic bridges that have extra cytoplasm close to the nuclei.
5. Spermatogenesis is the formation and maturation of sperm cells within the testes and the male reproductive organs.
6. The seminiferous tubules, which make up the majority of the testes' tiny, tightly coiled tubules, are where sperm cells are created.

Final answer: The difference between spermiogenesis and spermiation is that in spermiogenesis, spermatozoa are formed, while in spermiation, spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules.
