- 1. Name: Marsha.Hmiel Date: 06/02/2013 Instructor’s Name: Robert Carter Assignment: SCIE207 Phase 5 Lab Report Title: Taxonomy Lab to Show Organism Relationships Instructions: You will need to fill out the data table and answer a set of questions . When your lab report is complete, post it in Submitted
- 2. 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
- 3. Sample 3: Arthropoda Sample 4: Amphibia Sample 5: Aves Common Feature
- 4. 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
- 5. 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?
- 6. 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:
- 7. 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
- 8. 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
- 9. 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 nerve cord runs the length of the body Tiny anterior brain, nerve cord, ganglia, and extremely well- developed sensory organs Brain, nervous system, good reflexes Nervous and endocrine systems
- 10. Sample organism Phytoplankton Earthworm Fruitfly Frog Bird Table 2: Samples 6–10
- 11. Phylum/Division Sample 6: Reptilians Sample 7: Mammalia Sample 8: Bryophyta Sample 9: Gymnosperm Sample 10: Angiosperm Common Feature
- 12. Nutrition How does the organism break down and absorb food? Heterotrophic – Covered with scales Heterotrophic – Nuture their young with milk Autotrophic – Nonvascular plants
- 13. Autotrophic – Have needles and seeds but no flowers Autotrophic – Have flowers Circulatory System (Transport) How does the organism get what it needs to cells (open, closed, diffusion only)? Closed with 4 – chamber heart Closed with 4 – chamber heart Diffusion through cell walls and cell membranes Xylem and phloem
- 14. Xylem and phloem Respiratory System How does the organism get oxygen and release carbon dioxide? Diffusion through the lungs Diffusion through the lungs Diffusion through cell membranes Diffusion through stomata Diffusion through stomata Reproductive System
- 15. Does the organism use asexual or sexual reproduction (eggs, seeds, spores, placenta, type of fertilization)? Sexual: Eggs; internal Sexual: Placental, in-uterus development (internal) Sexual: Alternation of generations. Must be in a moist area for the sperm to swim to the egg Sexual: Alternation of generations. Pollen is the male sex cell Sexual: Alternation of generations. Pollen is the male sex cell Sexual: Excretory System How does the organism get rid of wastes and maintain an ionic balance of fluids? Kidneys, intestines, anus
- 16. Kidneys, intestines, anus None None None Growth and Development Does the organism go through metamorphosis, develop in an egg or uterus, or grow from seeds? Develop in eggs Develop in-uterus
- 17. Spores, not seeds Naked seeds in cones Seeds protected in pods, shells, fruit, and so forth Regulation How does the organism control body processes (hormones, nervous system)? Nervous and endocrine systems Big brain; well-developed nervous system and endocrine system none Hormones in apical bud, root, and stem
- 18. Hormones in apical bud, root, stem, and leaves Sample organism Snake Cat Moss Pine Tree Rose
- 19. Part 2: Using the completed data table, answer the following questions: What is common among all samples? What is common among organisms from samples 1, 9, and 10? What is common between the circulatory system of organisms from samples 5, 6, and 7, but different in organisms from sample 4? What is common in the respiration system of organisms from samples 2 and 4?
- 20. What gas is delivered to the respiratory system of organisms from samples 1, 9, and 10? Why? Which organisms are producers? Which organisms are decomposers? Look at the surface of your hand. You will see the skin and hair made up of protein called keratin . Which organisms did humans inherit that protein from?
- 21. Which organisms have blood?
