Water is pulled into a sponges body through ____ that are formed by porocytes.
Group of answer choices
ostia
choanocyte chambers
spongocoel
oscula
mesohyl
Sponges are organisms belonging to the phylum porifera. Sycon is an example of sponges. Sponges have a elaborate water canal system, which regulates entry and exit of water while retaining the food particles.
The porocyte cells are involved in pulling water inside the body of sponges via pores called ostia.
Hence, the correct choice should be:
ostia.
