Introduction To Living Environment

Introduction to Living Environment Mrs. N Naus Final Exam Review Sheet

Topic 1: Living vs nonliving Students should be able to identify and give an example of each characteristic of life Characteristics of life Cellularity Organization Growth and Development Heredity Evolution and Adaptation Responsiveness Metabolism Reproduction Require Energy Students should know the difference between living, nonliving and dead

TOPIC 2:The Scientific Method Students should be able to determine the difference between: 1- An observation and a hypothesis. 2- A theory and a hypothesis. 3- A theory and a law. 4- An independent vs dependent variable. 5- A control group vs an experimental group 6- Explain why a hypothesis is an educated guess 7- Set up a controlled experiment 8- Develop a conclusion

The Steps of the scientific method: Make an observation Research your observation Create an educated guess Perform an experiment consisting of An independent and dependent variable A control Group and experimental group Give the characteristics of a good experiment (large sample size and repeatability) Collect and Analyze data. Be able to read a data table or graph and create a valid conclusion. Formulate a valid conclusion based on the data. Be able to determine if the original hypothesis is true or false and why based on experimental data. TOPIC 3: The microscope Students should be able to determine the differences between compound light microscope and electron microscopes Label and give the function of each part of the microscope Give the characteristics of a microscope: Magnification:Total mag= mag ocular x mag of objective Field of view Resolution Depth of field Brightness Explain how these properties change when moving from low to medium to high magnification. Prepare a wet mount slide

1. The ability to see details or the sharpness of an image has to do with the ______of the microscope. 2. As magnification increases, field of view _____. 3. As magnification increases, brightness______. 4. As magnification increases, resolution ______. 5. What would the following letter look like under the microscope: p Topic 4: The Metric System Students should be able to understand and take measurements of the following table

Quantity Unit Instrument Mass Grams Triple beam balance Length Meter Meter stick,ruler Volume Regular Solid Cm3 LxWxH Irregular Solid Cm3 Water displacement Liquid mL or Liters Graduated cylindar Temperature Degrees Celsius thermometer

Remember the following: 1ml=1g=1cm3 Students should know how to convert in between units of the metric system KHDm,l,gDCM__Micro

1 mL=.01cL 10mL=1cL 1um=.001mm 1mm=1,000um 1cm=.01m 1m=100cm 1mm=.001m 1m=1,000mm 1Kg=1,000g 1g=.001Kg Topic 5: The cell students should be able to briefly describe organisms in each Kingdom. Archaebacteria Eubacteria Protista Plant Animal Fungi

Identify the difference between a prokaryote and a eukaryote Identify the different Eukaryotic organelles of the plant and animal cell Be able to identify and give the function for each organelle pictured below Students should be able to identify the chemical formulas of photosynthesis and cellular respiration

TOPIC 6: The cell membrane Why is the cell membrane a fluid mosaic? What are the functions of the cell membrane? Structure of the cell membrane: phospholipid bilayer (hydrophilic heads and hydrophobic tails) integral and peripheral proteins, glycoproteins and cholesterol Transport across the cell membrane Passive (diffusion, facilitated diffusion osmosis) Osmosis: hypertonic, hypotonic, isotonic, plasmolysis, lysis Active transport
