When your lab report is complete, post it in Submitted Assignment files. Part 1: Using the lab animation, fill in the following data tables to help you answer the questions that follow: Table 1: Samples 1–5 Phylum/Division Sample 1: Chrysophyta Sample 2: Annelida Sample 3: Arthropoda Sample 4: Amphibia Sample 5: Aves Common Feature Nutrition How does the organism break down and absorb food? Autotrophic Heterotrophic – Earthworms eat their way through dirt, so they are detritivores. Heterotrophic – Some are vegetarian, some are carnivorous, and some are decomposers. Heterotrophic – These are usually vegetarian as tadpoles and carnivores as adults. Heterotrophic Circulatory System (Transport) How does the organism get what it needs to cells (open, closed, diffusion only)? Diffusion only Closed with 5 aortic arches (hearts) Open circulatory system with a heart pumping hemolymph Closed with 3-chambered heart Closed with 4 – chambered heart Respiratory System How does the organism get oxygen and release carbon dioxide? Diffusion only Diffusion through skin Diffusion through tracheal tubes Diffusion through gills as a tadpole and through lungs and skin (especially) as adults Diffusion through the lungs Reproductive System Does the organism use asexual or sexual reproduction (eggs, seeds, spores, placenta, type of fertilization)? Asexual Hermaphrodites: One body has both sexes Sexual: His special organ called clitellum that moves from the front of the worm to the rear and then falls off, containing the eggs Sexual: Mostly internal fertilization Sexual: Mostly external fertilization; must be in water or very moist area Sexual: Eggs; internal Excretory System How does the organism get rid of wastes and maintain an ionic balance of fluids? Diffusion Nephridia in each segment; solid waste. Exits through the anus Malpighian tubeles Kidneys, intestines, anus Kidneys, intestines, anus Growth and Development Does the organism go through metamorphosis, develop in an egg or uterus, or grow from seeds? Start as small cells; grow bigger until division Start out as fertilized eggs, hatch into little worms that continue to grow, and then mature sexually into adults Complete (egg, larvae, pupae, adult) or incomplete (egg, nymph, adult) metamorphosis Metamorphosis; Egg, tadpole, adult Develop in egg Regulation How does the organism control body processes (hormones, nervous system)? The nucleus directs protein synthesis. Euglena have eye spots that can detect light Tiny anterior brain, ganglia, and the n.
