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- MulticellualrFungi- Multicellular Protists- Unicellular Moneran- Unicellular
Classification Lion- Tiger or Crocodile Pig- Primate or Squirrel Dog-Fox or Cat Cougar- Lion or Tiger Bony Fish- Penguin or Snake
List 3 forms of evidence scientists 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
CellsWhat are 3 differences between plant and animal cells?
Plant cells have a cell wallPlants have chloroplasts in their cells
The vacuole size is larger in plant cellsList all organelles and their functions(15)
Cytoplasm- supports and protects cell organelleCell membrane- protects, controls movement, and maintains homeostasis
Chloroplasts- uses energy from the sun to make foodCentrioles- play a role in cell division
Chromosomes- controls activities of the cell and pass on traitsCell wall- supports, protects, and allows H2O, O2, CO2 to pass through the cell
Nucleus- controls cell activitiesNucleolus- site where ribosomes are made
Nuclear membrane- controls movement of materials in and out of nucleusER- carries materials through cells (internal delivery system)
Ribosomes- produce proteinsMitochondria- breaks down sugar molecules into energy
Vacuole- stores food, water, and wasteLysosomes- breaks down larger food molecules and digests old cell parts
Golgi bodies- like a post office, it modifies and distributes proteins
CellsWhat 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 MethodList the steps of the scientific method in order?
