Some sponges are made of spongin, tough protein fibers, which is the supporting structure of sponges.

3. How do sponges feed?

Answer: filter feeding

Sponges feed by a method known as filter feeding. That is, sponges pick out small pieces of food as the water is drawn in.

4. What takes the nutrients from choanocytes and delivers them to the rest of the cells in a sponge?

Answer: amoebocyte

Amoebocytes take nutrients and deliver them to all the cells in a sponge. They crawl like amoeba, which has earned them their name.

5. What types of reproducton do sponges go through?

7. What do sponges use for defense and feeding?
