Bio 152 module 8
1. Sponge character- have specialized cells but no tissues have
istics totipotent cells
absorb nutrients through phagocytosis
spicules provide stuructural support
2. features of most muscles and nerve cells true
animals tissues
digestive cavity with internal digestion
3. muscles and nerve used for basic needs of life, food, habitat, mate, bulk flow
cells
4. true tissues added organization and functions, develop from embyronic germ layers in a
gastrula
5. intracellular diges- sponges use this for digestion of small particles
tion
6. extracellular diges- completed by most animals, within the body enzymes are released tion
7. cnidaria invertebrates that are famous for stining cells, have radial symmetry
8. cnidocytes stingin cells that tangle up or inject toxin into prey or predators
9. cnidarians have two germ layers, ectoderm and endoderm, their digestive cavit has just one
opening meaning their mouth and anus is one
10. bilateria animals with bilateral symmetry.
11. bilateral symmerty animals with distinct head and tail ends, bodies with a single place of symmetry
running between them at the midline
12.
