SEMESTER 1 EXAM – STUDY GUIDE CLASSIFICATION Binomial nomenclature – two-part scientific name (Genus species) Characteristics of living things (MRS. GREN) Levels of classification from kingdom to species (largest – smallest) Characteristics of organism within each of the 5 kingdoms o Animal – multicellular, eukaryotic heterotrophs o Plant – multicellular, eukaryotic autotrophs o Fungi – multicellular, eukaryotic heterotrophs (decomposers) o Protist – unicellular, eukaryotic heterotrophs o Moneran – unicellular, prokaryotic heterotrophs/autotrophs Dichotomous keys Evidence used for classification o Behavior and physical appearance o Method of reproduction, locomotion, diet and habitat o Cells and DNA analysis INSECTS Characteristics of arthropods and insects Special insect orders o Coleoptera – beetles (most diverse and populous insect order) How do insects make sounds? Insect mouthparts Metamorphosis – growth and development o Molting – shedding skin o Incomplete – egg, nymph, adult o Complete – egg, larva, pupa, adult IPM Steps of IPM o Identification – What is causing the problem? o Pest biology – Learn about the pest? o Monitor – How bad is the problem? o Threshold – How much is it going to cost? Is it worth it? o Tactic – Choose a method to control/get rid of the pest. o Evaluation – How well did it work? IPM Tactics o Cultural – take away items pest needs to survive o Physical – traps, burn nests, remove pest o Genetic – sterilize the males; genetically modify the pest or its food source o Biological – natural predators o Chemical – pesticides and insecticides o Regulatory – government laws and regulations MICROSCOPES Founding Fathers of Microscopy o Hooke – observed cork cells; coined the term “cell” o Leeuwenhoek – observed bacteria and protists o Janssen – first compound microscope Total magnification – eyepiece x objective lens Parts and functions CELLS Levels of organization from cell – organism Types of cells o somatic (body cells such as hair, skin, muscle, etc.) o gametes (sex cells such as egg and sperm) Eukaryotic cells vs. Prokaryotic cells Differences between plant and animal cells o Cell wall – gives a plant cell structure and support o Chloroplasts – organelle where photosynthesis occurs o Vacuole size – larger in plant cells used to store liquids All organelles and functions of organelle Diffusion, Osmosis and Active Transport SCIENTIFIC METHOD Steps of the scientific method – What takes place in each step? o Research/background information o State your purpose/problem question o State your hypothesis/make a logical prediction based on prior knowledge o Develop your procedure o Collect and record data (numerical and observable) o Analyze your results o Draw conclusions Experimental factors o Independent variable – the factor you control o Dependent variable – what you are testing/measuring/observing o Experimental group – the testing group o Control group – the group used for comparison o Controls – what is kept constant throughout the experiment
