1) Observe the slide labeled Starfish Embryonic Development. Label the following on the figures below: unfertilized ovum, morula, blastula, early gastrula, late gastrula, blastocoel, blastopore. 2) Observe the Poriferan specimens in the laboratory. Refer to the Invertebrates I specimens document for reference a) Know the characteristics of each sponge class (determined by the spicules). b) Determine whether they are asconoid, svconoid. or leuconoid body form. 3) Slides of longitudinal (Is) and cross (cs) sections of the Poriferans Scypha or Grantia. a) Label the following on the figures below: spicules, choanocytes, spongeocoel, radial canals, mesohy! b) Is Grantia/Scypha asconoid, syconoid, leuconoid? c) Describe the flow of water through a sponge. d) How do they feed? e) Why are choanocytes evolutionarily important?
