Question

question 8

what is the correct order of sperm development?

primary spermatocyte, secondary spermatocyte, spermatogonium, spermatid
spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid
spermatid, primary spermatocyte, secondary spermatocyte, spermatogonium
primary spermatocyte, secondary spermatocyte, spermatid, spermatogonium

Explanation:

Identify the stages of spermatogenesis

Spermatogonium (diploid stem cell) $
ightarrow$ Primary spermatocyte (diploid cell entering meiosis) $
ightarrow$ Secondary spermatocyte (haploid cell after meiosis I) $
ightarrow$ Spermatid (haploid cell after meiosis II) $
ightarrow$ Spermatozoon (mature sperm).

Evaluate the given options

• Option 1: Primary spermatocyte, secondary spermatocyte, spermatogonuim, spermatid (Incorrect order)
• Option 2: Spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid (Correct order)
• Option 3: Spermatid, primary spermatocyte, secondary spermatocyte, spermatogonuim (Incorrect order)
• Option 4: Primary spermatocyte, secondary spermatocyte, spermatid, spermatogonuim (Incorrect order)

Answer:

• Primary spermatocyte, secondary spermatocyte, spermatogonium, spermatid
• Spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid (Correct answer)
• Spermatid, primary spermatocyte, secondary spermatocyte, spermatogonium
• Primary spermatocyte, secondary spermatocyte, spermatid, spermatogonium
