  1. The 3 statements of cell theory are:
    • - all living organisms are made up of one or more cell
    • - the cell is the basic organizational unit of life
    • - all cells come from pre-existing cells
  2. The nucleus:
    • contains chromosomes
    • is the control centre of the cell
    • as 23 pairs of chromosomes in humans, 23 form dad and 23 from mom
  3. Chromosomes contain:
    A single molecule of DNA
  4. DNA is divided up into:
  5. DNA is important because:
    It controls our features
  6. The function of the cell membrane is:
    Separates inside of cell from external enviroment
  7. The function of cytoplasm is:
    Containing all life supporting materials inside cell membrane
  8. The function of the mitochondria is:
    Energy is released from glucose
  9. Function of Ribosomes is:
    help to produce proteins
  10. Function of endoplasmic reticulum is:
    transport materials
  11. Function of vesicles is:
    Store materials
  12. Function of Nucleus is:
    Control Centre
  13. Function of vacuoles is:
    Transport molecules
  14. A transgenic organism is:
    An organism whose genes have been altered and combined with genes of another organism for unknown benefits or consequences
  15. Cell division is:
    • The main process by which celled organisms reproduce
    • Multi-cellular organisms increase the number of cells and repair and replace old and damaged cells
  16. Diffussion is:
    The movement of molecules from an area of high concentration to an area of low concentration
  17. Mitosis is:
    Cell division of non-sex cells where the parent cell divides into two identical daughter cells
  18. The 2 main stages of the cell cycle are:
    Growth and cell division
  19. A cells life is broken into:
    • Interphase
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
  20. 90% of the cell's life is spent in"
  21. Interphase s broken into:
    • Growth
    • Synthesis
    • Growth 2
    • Mitosis
  22. During Interphase:
    • The cell replicates its DNA
    • The cell grows
  23. During Prophase:
    • Chromatin condenses into smaller chromatids
    • The nucleus membranes break apart
    • The chromatids begin to attach to spindle fibers
  24. During Metaphase:
    • The chromatids line up along the midline of the cell
    • chromatids fully attach to spindle fibers
  25. During Anaphase:
    • The chromatids separate from their partner
    • The chromatids are pulled to opposite ends of the cell
  26. During Telophase:
    • The chromosomes uncoil
    • spindle fibers disappear and the nuclear membrane appears
  27. The point of checkpoints is:
    • To make sure there are enough nutrients
    • to make sure the DNA has replicated
    • to make sure the DNA is not damaged
  28. Cancer happens when:
    damaged cells ignore the stop signs and divide repeatedly
  29. A cell is:
    A grouping of organelles
  30. A tissue is:
    A grouping of a specific type of cell
  31. An Organ is:
    A grouping of different kinds of tissues for a specific purpose
  32. The 3 types of Tissues in plants are:
    • Dermal
    • Ground
    • Vascular
  33. The 3 types of Organs of the plant body are:
    • Leaves
    • Roots
    • Stem
  34. The purpose of the leaf is:
    To provide a large surface area for photosynthesis
  35. Water is transported through plants in the xylem through:
    Root Pressure
  36. In leaves, liquid turns to:
  37. Sugars are transported by the:
  38. The purpose of the stem is:
    Physical support and xylem pipes
  39. The purpose of the root is:
    • Anchoring support
    • nutrient and water uptake
  40. Factors that influence cell specialization are:
    • Effect of cytoplasm
    • Effect of environmental conditions
    • Effect of neighboring cells
