First letter in the genus capitalized, a comma between the two names,
and both words italicized
Name all seven characteristics of living things (MRS. GREN)
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition
What is the forth largest classification level?
Order
Name the five kingdoms
Animal, Plant, Fungi, Protists, Moneran,
Name Whether Unicellular or Multicellular
Animal- Multicellular
Plant- Multicellualr

Cells and DNA analysis

4. Insects Egg, larva, pupa, adult Complete What is an arthropod?
An invertebrate animal of the large phylum Arthropoda, such as an insect, spider, or crustacean.
Name the most diverse and populous order
Coleoptera
Name 4 characteristics of an insect
Head, thorax, abdomen, two pair of wings, an exoskeleton, three pairs of legs, compound eyes, mandibles, and a pair of antenna

5. Microscopes
Name the 3 founding fathers Hooke, Leeuwenhoek, Janssen What did Janssen do? Made the first compound microscope

6. <<<Plant Cell
Cells
Describe the difference between somatic and gametes cells Somatic cells are body cells and gametes cells are sex cells What main feature are Prokaryotic cells missing They don’t have a nucleus
<<<Plant Cell

7. Cells
What are 3 differences between plant and animal cells? Plant cells have a cell wall Plants have chloroplasts in their cells The vacuole size is larger in plant cells List all organelles and their functions(15) Cytoplasm- supports and protects cell organelle Cell membrane- protects, controls movement, and maintains homeostasis Chloroplasts- uses energy from the sun to make food Centrioles- play a role in cell division Chromosomes- controls activities of the cell and pass on traits Cell wall- supports, protects, and allows H2O, O2, CO2 to pass through the cell Nucleus- controls cell activities Nucleolus- site where ribosomes are made Nuclear membrane- controls movement of materials in and out of nucleus ER- carries materials through cells (internal delivery system) Ribosomes- produce proteins Mitochondria- breaks down sugar molecules into energy Vacuole- stores food, water, and waste Lysosomes- breaks down larger food molecules and digests old cell parts Golgi bodies- like a post office, it modifies and distributes proteins

8. Cells
What is diffusion? Diffusion is the process of which molecules move from an area of higher concentration to a lower concentration. How is osmosis related to diffusion? Osmosis is the diffusion of water. What is active transport? Active transport is the movement of materials through a cell membrane using cellular energy. What are the three things for photosynthesis to occur? Water, sunlight, and carbon dioxide What is respiration? The process of which cells obtain energy from glucose.

9. Scientific Method List the steps of the scientific method in order?
Problem Question
Research
Hypothesis
Develop your procedure
Collect and record Data
Analyze your results
Draw Conclusion
What takes place in each step?
Problem Question- developing question
Research- getting background information
Hypothesis- making an educated guess based on research
Develop your procedure- conduct your experiment and
Collect and record Data- record your results from your experiment
Independent variable- The factor you control
Dependent variable- what you are testing/measuring/observing
Experimental group- what testing group
Control group- the group used for comparison
Controls- What is kept constant throughout the experiment

10. Thanks for Participating!!!!!
Good luck on the test!
