Quincy and Leon are comparing sponges and cnidarians. Quincy says that spicules in sponges are similar to stinging cells in cnidarians. Leon disagrees.
Which best explains who is correct?
Leon is correct, because sponges have stinging cells and cnidarians have spicules.
Quincy is correct, because both spicules and stinging cells can be used to protect against predators.
