3. Define mitosomes and hydrogenosomes. What is the function of each? What is the evidence that these organelles are derived from mitochondria? What are some specific organisms that possess each of these organelles? 4. Describe/draw the âtypicalâ life cycle of a Poriferan. Include sexual and asexual reproduction and dispersal. 5. How are metazoan synapomorphies related to the evolution of a multicellular organism? What are some other traits that generally characterize metzoans (not necessarily synapomorphies or unique to metazoans)? 6. Draw a diagram or provide a detailed, comprehensible explanation of the body structure and movement of water through an asconoid sponge. What cells are responsible for generating these water currents? Is current through the sponge dependent on water flow in the external environment?
