Ms. Phillips 7R Review Sheets REVIEW - Life 1. If two organisms have very few characteristics in common, are they more likely to be in the same species or kingdom? Why? 2. What are the 7 levels of classification in order from largest to smallest? 3. What are the 5 kingdoms? 4. What kingdom do bacteria belong to and why? 5. What kingdom does an ameba belong to and why? 6. What is the difference between a heterotroph and an autotroph? 7. What kingdom do mushrooms belong to and why? 8. Canis lupus is the name for wolves. Which part represents their genus? Which part represents the species? 9. Complete the chart Name of Life Process Process Description energy production movement of organism cells increasing in number control and coordination removal of wastes forming larger molecules flow of materials in an organism creating more of our own kind REVIEW Cells: 11. 1. Label the cell parts: 1. 10. 2. 3. 9.__________ 8. 7. 6. 4. 5. Identify the organelle: 2. ____________________ is the organelle responsible for transport of materials inside the cell. 3. The function of ribosomes is _____________________________________ 4. _____________________ is the organelle that controls all the activities of the cell. 5. The cell membrane is responsible for _____________________________ 6. _____________________ is the organelle that breaks down (digests) cellular materials. 7. Vacuoles are the sites for _____________________ of cellular material. 8. The genetic information of the cell that is also called the hereditary information that is in the nucleus is the _______________ 9. ________________________ is the jellylike material found inside in the cell membrane. 10. The ______________________ gives the plant cells its ability to perform photosynthesis and its green color. 11. List the organelle(s) that are only found in animal cells. 12. List the organelles that are only found in the plant cells. 13. Cellular transport is _____________________________________________ 14. Name the two types of cellular transport. 15. How are diffusion and osmosis different? 16. How are active and passive transport different? 17. Why do some molecules cross the cell membrane and others do not? 18. Define selectively permeable. 19. Label the following situations as active transport, osmosis, or diffusion: a. fresh water moves into a single celled organism b. you smell delicious cookies cooking in another room c. molecules are “pumped: out of a nerve cell. Review: Scientific Method List the steps of the scientific method: a) b) c) d) e) f) _________________ _________________ _________________ _________________ _________________ _________________ The Strange Case of BeriBeri In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included weakness and loss of appetite, victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with beriberi. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria. a. State the Problem b. What was the hypothesis? c. How was the hypothesis tested? d. What is the independent variable? e. What is the dependent variable? f. Identify the control group. g. Should the hypothesis be supported or rejected based on the experiment? One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case. He found that polished rice lacked thiamine, a vitamin necessary for good health. h. What should be the new hypothesis? Review: Metric system 1. 2. 3. 4. 5. 6. 100 mm = ______ cm 34 km = _______ m 257 cm = ______ hm 5.4 millimeters = ______m 3.7 kilometers = ___m 5.0 meters = _____cm Review -microscopes: • Microscope parts and functions • Microscope usage • Microscope measurement • Total Magnifications MICROSCOPE measurement 1. 2. 3.5 mm Field of view = Length of the object = __________mm ________um _______mm ________um 3. 4. Field of view = 1400 um Length of specimen = 1000um Length of the organism = __________mm__________um ________mm ________um 5. Field of view = 1.5 mm Length of 1 cell = _______um 6. Length of cell = _________um Review Lab Skills: 1. Circle unsafe practices in the lab State the function of each tool and be able to identify: 1. Beaker 2. Bunsen Burner 3. E. Flask 4. funnel 5.
