Figure 1. Cross section of spermatogenesis. Use this figure to answer the question below. Look at Figure 1 (above) and focus your attention to the few steps of spermatogenesis that are visible in this diagram (other steps are present but not shown here). Is this figure showing portions of spermatogenesis from a mammal or non-mammal? Explain your reasoning. Think

Solution

Mammals are not hermaphrodites; they have separate sexes. The figure shows spermatogenesis but also shows oocytes. Thus, the figure is from a hermaphroditic, non-mammal, such as an earthworm.
