Based on the provided text and Figure 46.7, which of the following best describes the primary function of spermathecae in female fruit flies?

  • A: They are the primary sites of egg development.
  • B: They produce the fluid necessary for sperm motility.
  • C: They store sperm for extended periods, allowing fertilization to occur later.
  • D: They facilitate the direct transfer of sperm from the male during copulation.

Explanation

The text explicitly states: 'After mating, sperm are stored in the spermathecae, which are connected to the uterus by short ducts. The female uses a stored sperm to fertilize each egg as it enters the uterus before she passes the egg out through the vulva.' It also mentions that sperm 'may be kept alive and stored for extended periods, a year or more in some cases.'
