Show Answers:

  1. MIcrometer
    1000 times smaller than a millimeter
  2. red blood cell
    a small cell that carries oxygen through the blood system
  3. ostrich egg
    the largest cell
  4. diffusion
    the splitting of a cell
  5. dna content
    amount of dna in a cell
  6. mrna
    messenger rna
  7. multinuclated
    multiple nucleus's
  8. chromatin
  9. chromisomes
    bound together
  10. surface area to volume
    surface area is more than mass
  11. histones
    any group of chromotin
  12. cell cycle
    the splitting of cells
  13. Interphase
    the resting between divisions of the cell
  14. g1
    long growth period of the cell cycle called
  15. sythisis
    cell grows in size and synthesizes
  16. g2
    • For most cells, the majority of their life is spent
    • in interphase. It is during this time that the cell carries out most
    • of its normal functions, such as growth and protein synthesis. Interphase
    • has three stages called G1, S and G2. In many tissues,
    • such as in the brain, most mature cells will remain in interphase throughout
    • their lives.
  17. prophase
    the first stage of cell division
  18. metapase
    • the
    • second stage of cell division, between prophase and anaphase, during
    • which the chromosomes become attached to the spindle fibers.Translate metaphase toUse over time for: metaphase
  19. anaphase
    • the
    • stage of meiotic or mitotic cell division in which the chromosomes move
    • away from one another to opposite poles of the spindle.Translate anaphase toUse over time for: anaphase
  20. Telophase
    • the
    • final phase of cell division, between anaphase and interphase, in which
    • the chromatids or chromosomes move to opposite ends of the cell and two
    • nuclei are formed.OriginMorelate 19th cent.: from Greek telos ‘end’ + phase.Translate telophase toUse over time for: telophase
  21. chromotids
    an atom or group whose presence is responsible for the color of a compound.
  22. spindle fibers
    thin fibers
  23. cyto kinises
    the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
  24. animal cell division
    The process by which a cell divides to form two daughter cells
  25. daughter cells
    cells that have been split
  26. cancer
    a big group of cells
  27. mutations
    difformities in cells DNA
  28. HPV
    Desiese that is transmitted by mutattions
  29. predispositions
    a liability or tendency to suffer from a particular condition, hold a particular attitude, or act in a particular way.
  30. contact inhibition
    • Normal somatic cells when grown in culture will become growth inhibited
    • when they encounter another cell. The cells in our bodies are governed
    • by growth control mechanisms and cell senescence.
  31. cyclins
    • any
    • of a number of proteins associated with the cycle of cell division that
    • are thought to initiate certain processes of mitosis.Origin
  32. INternal regulatiors
    on inside of cell
  33. External Regulators
    on outside of cells
  34. growth factors
    the factors if deciding its ok for the cell to grow if it has too much DNA
