Based on Figure 33.3 and the accompanying text, which of the following cell types or structures is correctly matched with its primary function?

  • A: Epidermis: Responsible for generating water currents for feeding.
  • B: Choanocytes: Manufacture tough skeletal fibers like spicules.
  • C: Amoebocytes: Transport nutrients, produce skeletal fibers, and can become other cell types.
  • D: Spongocoel: The main excurrent opening for water to exit the sponge.

Explanation

Figure 33.3, specifically label 7, and the text explicitly state that amoebocytes transport nutrients, produce skeletal fibers spicules or spongin , and can become any type of sponge cell as needed. This makes option C the correct match.
