  1. Mitosis
    Division of the nucleus.
  2. 4 Stages of Mitosis
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
  3. Prophase
    Chromatin become chromosomes, nuclear envelop and nucleolus disappears, centrioles appear and go to opposite sides (poles) of the cell, and spindle fibers form between the centrioles forming an aster.
  4. Metaphase
    Chromosomes line up in the middle of the cell ( equator)
  5. Anaphase
    Chromosomes are pulled apart
  6. Telophase
    Spindle fibers and centrioles disappear, nuclear envelope and nucleolus reappear, chromosomes unwind and become chromatin, cell begins to pinch inward
  7. Cytokinesis
    Division of the cytoplasm
  8. Meiosis
    Division of the sex cell
  9. Meiosis
    Explain the reduction division
    There are two nuclear reductions which reduce the number of chromosomes by half.
  10. Meiosis is responsible for
    Genetic Diversity
  11. Somatic Cells contain how many chromosomes
    46
  12. Why is the 46 chromosomes in the somatic cells called a "Diploid Number?"
    Chromosomes in somatic cells occur in pairs, each number of the pair is present so there are 23 pairs, or 46 chromosomes.
  13. How many Chromosomes are in a gamete?
    23
  14. Haploid
    When one member of each pair is present= number of chromosomes
  15. Mitosis

    Brief description
    • Occurs in Body cells
    • Makes Identical cells
    • One Nuclear Division

    ( My cells)
  16. Meiosis- Brief Discription
    • Occurs in sex cells
    • allows for genetic deversity
    • Two nuclear divisions
    • Reduction division

    ( ME)
  17. What invention revolutionized many things in the modern medical world?
    Microscope
  18. Viruses are _______.
    Living. They are not made up of a cell(s)
  19. Cell
    Basic Unit of life
  20. Plasma Membrane
    • Membranous-
    • Serves as the boundary of the cell. Maintains it integrity. Protein molecules embedded in the plasma membrane performs various functions; for examples, they serve as markers that identify cells of each individual, as receptor of molecules for certain hormones and other molecules, and as transport mechanisms.
    • Covers the entire cell.
  21. Endoplasmic Reticulum Rough
    Ribosomes attached to rough ER synthesize proteins that leave cells via the Golgi apparatus;

    Membranous
  22. Smooth ER
    • Smooth ER synthesizes lipids incorporated in the cell membranes, steroid hormones, and certain carbohydrates used to form glycoproteins. Also removes and stores Ca++ from the cell's interior.
    • Membranious
  23. Golgi Apparatus
    • Synthesizes carbohydrate, combines it with protein and packages the product as globules of glycoprotein.
    • Membranious
  24. Vesicles
    Temporarily contain molecules for transport for later use.; Membranous
  25. Lysosomes
    Digestive Enzymes break down defective cell parts and ingested particles; a cells digestive system.; Membranous
  26. Peroxisomes
    Enzymes that detoxify harmful substances in the cell.; Membranous
  27. Mitochondria
    Catabolism; ATP synthesis, a cell's power plant..; Membranous
  28. Nucleus
    Houses the genetic code, in witch in turn dictates protein synthesis; therefore playing an essential role in other cells activities, namely, cell transport, metabolism, and growth..; Membranous
  29. Ribosomes
    Site of Protein Synthesis. A cell's protein factories. NON-membranous
  30. Proteasomes
    Destroys misfolded or otherwise abnormal proteins manufactured by the cell. " Quality control" for Protein Synthesis.
  31. Cytoskeleton
    Supporting frame work of the cell and its organelles; function is cell movement.
  32. Centrosome
    Acts as the microtubule organizing center of the cell. Centrioles assist in the forming of microtubules.
  33. Microvilli
    Tiny Fingerlike extensions that increase a cell's absorptive surface area
  34. Cilia and Flagella
    Cilia move substances over the cell surface or detect changes outside the cell; flagella propel sperm cells.
  35. Nucleolus
    site of formation of ribosome subunits
  36. Organelles
    Little organs
  37. Where are ribosomes located?
    Cytoplasm and Rough ER
  38. Cellular Respiration
    • Cells break down
    • Glucose ( C6H12O6)
    • Nutrient that has been converted to glucose or one of its simpler products into carbon dioxide (CO2) and water (H20)
    • Refer to page 105)
  39. 3 smaller pathways are chemically linked together to form the larger catabolic pathway known as cellular respiration
    • Glycolysis
    • Citric Acid Cycle
    • Electron Transport System
  40. You can't make ATP without
    Oxygen
  41. Carbondioxide is bi-product from
    ATP
  42. Anarobic Cellular Respiration
    Requires less ATP
  43. Latic Acid
    • Bi-product of ACR
    • This is also the burn you feel during exercise.
  44. Peroxisomes are found in the
    Liver
  45. Cytosekelton
    Helps provide structure
  46. Sperm -> Ovum -> Zygote
    Male 23 -> Female 23 -> Baby 46
