Classification
What is the proper format to write a scientific name?
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
 Fungi- Multicellular
 Protists- Unicellular
 Moneran- Unicellular

Use when classifying animals.
 Behavior
 Physical Appearance
 Methods of reproduction
 Locomotion (movement)
 Deit
 Habitat
 Cells and DNA analysis
Insects
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
Name the three different types of mouthparts
Siphoning, piercing, sponging
Name the 3 types of metamorphosis
Molting, Incomplete, Complete
What stages are included in incomplete metamorphosis?
Egg, nymph, adult
Egg, larva, pupa, adult
Complete
Microscopes
Name the 3 founding fathers
Hooke, Leeuwenhoek, Janssen
What did Janssen do?
Made the first compound microscope
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
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
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.
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
Analyze your results
Draw Conclusion

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
Good luck on the test!
