  1. 3 parts of cell theory? Types of cells it applies to?
    All life is made up of cells, all cells are made from pre-exhisiting cells, cells are the most basic form of life

    Applies to all cells
  2. contractile vacuole
    • gets rid of excess water, found in some protists
    • prevents bursting of cell and dilution
  3. central vacuole
    stores mostly water, only one, only found in plants
  4. Funtion of vacuole
    storage containers of various substances
  5. Funtion of smooth er
    synthesizes lipids, stores calcium, detoxifies enzymes
  6. Funtion of rough er
    makes more membrane, modifies proteins
  7. Funtion of cell wall
    rigid, tough layer, keeps cell from bursting, made of cellulose
  8. Funtion of peroxisome
    break down fatty acids, H2O2 (catalase), synthesis of myelin, produced by ER
  9. Funtion of lysosome
    digests food particles to release nutrients to cell, destroys damaged organelles, contains powerful digestive enzymes
  10. Funtion of nucleus
    encloses DNA, control center of the cell
  11. Funtion of ribosomes
    makes proteins using instructions from DNA
  12. Funtion of golgi body
    recieves vesicles for the ER and finishes, sorts, and ships proteins
  13. Funtion of mitochondira
    site of cellular respiration and creates energy for the cell (ATP)
  14. Funtion/parts of cytoskeleton
    • function: help with support/ internal structure and movement
    • parts: microfilaments, intermediate filaments, microtubules
  15. Funtion of chloroplast
    make food through photosynthesis
  16. Funtion of cytoplasm
    hold structures in place within the cell: metabolic chemical reactions occur here
  17. Funtion of cell membrane
    regulates what enters and leaves the cell
  18. Chromatin
    uncoiled DNA, usually in this form
  19. Chromosome
    • coiled DNA, contains genes
    • all humans contain 46 in each cell except red blood cells and gametes
  20. Importance of large surface area in cell
    Absorb nutrients, oxygen, water, etc. and dispose of waste
  21. Protist
    unicellular eukaryote
  22. Ex: prokaryotes and eukaryotes
    • pro: bacteria
    • eu: plants, animals, fungi, protists
  23. Prokaryotes vs. eukaryotes
    • Pro: small, unicellular, simple, no membrane bound organelles, no nucleus, reproduce asexually
    • Eu: Larger, mulit/unicellular, more complex, membrane bound organelles, nucleus
  24. Parts in all cells?
    Cell membrane, genetic information (DNA), ribosomes, cytoplasm
