  1. What is Taxonomy?
    The branch of biology concerned with identifying, naming, and classifying organisms is part of systematics
  2. Who developed the system of giving organisms a two-part name called binomial nomenclature?
    Carolus Linnaeus
  3. What hierarchial levels of classification are used to name an organism in binomial nomenclature? Which one is written first?
    • 1.) Genus - can contain many species
    • 2.) Species - refers to one species within that genus
  4. To what genus does the timber rattlesnake (Crotalus horridus) belong?
    Crotalus
    1. List the eight levels of hierarchal classification from most inclusive to least inclusive.
    Domain-Species- Genus- Family- Order- Class- Phylum- Kingdom
    1. What
      major factor separates the members of the Domain Eukarya from Eubacteria
      and Archeabacteria?
    Cell Wall
  5. Write the Kingdom of the organisms that fit the
    following descriptions:
    • a. Multicellular,
    • autotrophic, eukaryotic organism
    • -Kingdom
    • plantae

    • b. Multicellular,
    • have cell walls containing chitin, produce spores
    • – Kingdom
    • Fungi

    • c. Multicellular,
    • heterotrophic, eukaryotic organism that must ingest their food
    • –Kingdom
    • Anamalia
    • d. Unicellular,
    • prokaryotic organisms that can live in extreme conditions
    • -Protists
  6. What is the name given to the life cycle of plants
    which includes a sporophyte generation and a gametophyte generation?
    Alteration and Generation
  7. Flowers are just modified what?
    Leaves
  8. List the major parts of a flower and discuss the
    roles of each (be sure to include reproductive and non-reproductive parts)
    • 1) Sepals – Protects the flower bud
    • 2) Petals – attract pollinator
    • 3) Stamens – pollen grain develops
    • 4) Carpel – Contains the stigma, style, and ovary

    1. From
      what plant part does the seed develop?

    Carpel - the ovary becomes a seed
  9. What structure develops into a fruit in angiosperms?
    Ovary
  10. To what structure on the flower is pollen transferred during pollination?
    Stamens
  11. What are the major photosynthetic organs of the
    plant? In what tissue of these organs does photosynthesis take place?
    The leaves and the mesophyll; leaves
  12. What is the function of the waxy cuticle on the surface of plant leaves?
    To prevent water loss
  13. What are some major differences between angiosperms and gynposperms?
  14. 1)
    • Flower dispersal as
    • seeds, flowering land plant-seeds are born within a fruit
  15. 2)
    • A type of woody seed
    • plant, seeds are not enclosed by a fruit, and usually born in cones
  16. In what structure of the flower is the pollen produced?
    Anther
  17. What are stomata? What is their function?
    Little openings that allow gas exchange
  18. What structures on the roots of plants help to increase surface area for absorption?
    Root hairs
  19. List the major differences between monocots and
    dicots (eudicots). Be sure to include: leaf venation, vascular bundles, flower
    parts, seed leaves, and types of roots.
    • 1)
    • Monocot – members have 1
    • embryonic leaf, parallel-veined leaves, scattered vascular bundles, flower
    • parts in three or multiples of three, and root xylem and phloem in a ring
    • 2)
    • Dicots – members have 2
    • embryonic leaves, leaves form a net pattern, vascular bundles in a distinct
    • ring, flower parts in fours or fives and their multiples, and root phloem
    • between arms of xylem
  20. Give an example of some taproots we eat.
    Carrots, beets, turnips, and radishes
