Answer the following questions on sponges and cnidarians.
- What is the main function of each of the three types of cells that make up a sponge's body?
- What are the functions of the inner and outer tissue layers in a cnidarian?
- What are the advantages of a gastrovascular cavity to the body functions of a cnidarian?
- How do sponges and cnidarians defend themselves against predators? What is different about the methods used by each?
- Some sponges have the ability to reassemble themselves after they are experimentally broken down into individual cells. What might this suggest about the origin of multicellularity in animals?
