Answer:
Porifera use their flagella to eating.
Explanation:
Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.
Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.
The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.
The other options are not correct:
- <em>Porifera is immobile, so the flagella do not participate in swimming.</em>
- <em>Flagella do not participate in the reproductive process of marine sponges.</em>
