Show Answers:

  1. dependent variable
    distance from ball from target. date that you are collecting
  2. constant
    distance from target, number of throws
  3. experimental group
    group that is tested
  4. control group
    group that you are not testing. serves as a comparison to the experimental group
  5. independent variable
    factor that you test or alter during the experiemtn
  6. dependent variable
    factor that you measure- type of data that you are collecting
  7. alteration of generations
    • life cycle of plants. haploid and diploid stage.
    • Diploid stage- plants produce sporophytes- which undergo meiosis to produce unicellular haploid spores
    • The Haploid spres divide by mitosis to produce a gamotophyte. The gametophyte produces seperate male and female gametes that fuse to form zygote, which develope from an embryo into the diploid sporophyte.
  8. 4 plant groups
    • Bryophytes- moss, liverworts, lack roots. leaves, stems
    • Seedless vascular plants- ferns, club mosses,
    • Gymnosperm-
    • Angiosperms- flowering plants
  9. Fungi
    • Can be decomposers, parasites, predatory, mutualistic.
    • Produce sexually or asexually
  10. Major Fungi Groups
    • Chytridomycota- aquatic
    • Zygomycota- decomposers of material in soil. zygospore.
    • Ascomycota- reproduce asexually by spores. ascus.
    • Basidiomycota- produce basdium
  11. Symbiotic relationships involving fungi
    • lichens- formed from interactions of fungus with algae or cyanobacteria
    • Myocorrhizae- formed when a fungus interact with roots of a plant
  12. Forest Stratification
    • canopy- tallest
    • subcanopy- trees of medium hight
    • ground cover- short plants
  13. prokaryotic cells
    • bacteria- single cells. pathogens. decompose and recycle
    • Archaea- single celled. inhabit extreme enviorments

    Lack nucleas and organelles
  14. Eukaryots
    • Protists- single celled. amoebas. seaweed.
    • Fungi
    • Animals
    • Plants
  15. structures of eukaryotes and prokaryots
    • plasma membrane
    • ribosomes
    • dna
  16. ribosomes
    coordinate protien synthesis
  17. chloroplast
  18. mitochondria
    cellular respiration
  19. compound microscope
    • 40x-1000x
    • cells of animals, plants, fungi, some bacteria
    • cell structures
  20. steroscopic microscope
    • 7x-30x
    • 3d view of object becase light hitting the surface of a specimen is reflected up through the lens system of dissecting microscope
  21. electron microscope
    • 1,000,000x
    • can distinguish 2 objects close together
  22. depth of field
    the thickness of a specimen that is in focus at a specific magnification
  23. magnification
    calculated as the magnification of the ocular lens (10x) times the magnification of the objective lens (the integer that is printed on the side of the lens)
  24. functional group
    a group of atoms attached to a carbon chain
  25. monomer
    • smallest subumit of a biological molecule
    • glucose
  26. polymer
  27. carbs
    • Glucose- mono
    • Fructose- mono
    • Sucrose- di
    • Starch- poly

    C, H, O
  28. lipids
    • fats/oils/waxes
    • phospholipids
    • steroids

    C, H, O
  29. Protiens
    amino acids made up of C with 4 functional groups (H, NH2, COOH, variety)
  30. catechol oxidase formula
    Catechol + .5 02 -- (C.o)---> Benzoquinone + H20
  31. stomata
    • lets co2 into internal spaces of leaf, which is then sued for photosynthesis
    • When it closes, CO2 is no longer available for photosynthesis
  32. spongy mesophyll
    where some photosynthesis takes place
  33. palisade mesophyll
    contains chloroplast, where majority of photosynthesis takes place
  34. guard cell
    allow co2 to enter cell for photosythesis
  35. cuticle
    barrier that protects plants
  36. angiosperm
    has flowers, vascular, monocot, dicot, has seeds
  37. gymnosperm
    vascular, has seeds
  38. seedless vascular plant
    vascular, require water for fertilization
  39. bryophyte
    vascular, require water for fertilization
