Given what we know, we can confirm that Ostia are important to sponges because they pull water into the sponge through the beating of their flagella.
<h3>What are Sponges?</h3>
- A sponge is an aquatic multicellular organism.
- Morphologically, they are very simple organisms, lacking complex structures.
- One structure that they do possess is the Ostia.
- The Ostia are a series of pores located throughout the body of the sponge.
- They serve to draw in water through the beating of multiple flagella.
Therefore, we can confirm that since the Ostia of the sponge are used to pull water into the sponge through the beating of their flagella, the correct answer would be option D.
