During spermatogenesis, sperm cells receive what amount of cytoplasm?

• A. Equal
• B. Most
• C. None
• D. Little

Answer: (A)

During spermatogenesis, the division that produces four haploid spermatids happens with incomplete cytokinesis, so the cytoplasm is shared among the developing cells via cytoplasmic bridges. This means each of the four sperm precursors ends up with roughly the same amount of cytoplasm. Later, in spermiogenesis, most of that cytoplasm is shed, leaving mature sperm with very little cytoplasm. So, the best answer reflects that equal distribution of cytoplasm occurs during the division stages, before the final maturation reduces cytoplasm in the mature cells.
