What is true about all sponges without exception?

1. They are all marine
2. They have flagellated collar cells
3. They have a mixed skeleton consisting of spicules and spongin fibres
4. They reproduce only asexually by budding

Correct answer: They have flagellated collar cells

Solution

All sponges possess choanocytes, or flagellated collar cells, which create water currents and trap food particles. The other choices are not true of every sponge because habitat, skeleton composition, and reproductive mode vary among species.
