| Porifera lack symmetry and __________ which distinguishes them from other phyla | tissues |
| How do sponges reproduce? | budding |
| Sea anemones have ____ symmetry | radial |
| True or false: Sponges are unicellular | false |
| What does gastropod mean? | stomach foot |
| What secretes the shell in some molluscs? | mantle |
| Organisms with three germ layers are called | triplobastic |
| What maintains an organisms form with water pressure? | hydrostatic skeleton |
| Sensory organs focused to one area is called | cephalization |
| What is the radula used for? | tearing flesh and eating |
| Cestoda are also known as? | tapeworms |

| How do bivalves move? | by their foot |
| What circulatory system do most cephalopods have? | closed |
| What is the function of the funnel in cephalopods? | to expel water either forwards or backwards for movement |
| Which cephalopod has two pairs of gills? | nautiluses |
| What is the function of the brachial hearts in cephalopods? | located at the base of the gills, they increase blood pressure in the circulatory system |
| Is there a larval stage in cephalopods? | no, eggs develop directly into juveniles |
| What is the larval stage of marine molluscs? | trochophores |

| The group of cells that can detect light? | eye spot |
| What is the "first hunter"? | flatworm |
| What is a group of nerve cells that act like a brain controlling the nervous system? | ganglia |
| True or false: color vision is important and useful in cephalopods? | false |
