According to the information provided in Figure 29.17 and its accompanying text, what is a crucial aspect of fertilization in most fern species?

  • A: Sperm are dispersed by wind to reach the eggs.
  • B: Fertilization typically involves sperm and eggs from the same gametophyte.
  • C: Sperm require water to swim to the eggs, guided by chemical attractants.
  • D: The zygote develops into a mature gametophyte.

Explanation

Point 3 in the diagram's text explicitly states, "Sperm use flagella to swim to eggs in the archegonia. An attractant secreted by archegonia helps direct the sperm." This highlights the dependence on water for sperm dispersal and the role of chemical signaling.
