    Where are the hydrophillic and hydrophobic regions?
    Yellow tails on inside of membrane are HYDROPHOBIC and purple phospholipid heads on outside are HYDROPHILLIC
  2. Image Upload 4
    Which has the more active nucleus?
    The cell on the left has more Euchromatin, and is therefore more active compared to the cell on the right.

    Which areas are heterochromatic, euchromatic and where is the nucleolus?
    • Image Upload 8
    • Euchromatin = EU
    • Heterochromatin = HC
    • Nucleolus = NU

    What type of cytoskeleton structure is this? and what does it do?
    Microtubules - how vesicles move within the cell
  9. Image Upload 20
    What type of cytockeleton structure is this? What is the function?
    • Microfilaments- forms pockets in cell membrane when things move in and out of cell, responsible for membrane activity like endo and exocytosis
    • Ex: actin or myosin
  10. Image Upload 22
    What type of cytoskeleton structures are these? Function?
    Intermediate filaments- provie strength and define the shape of the cell as a whole
  11. Image Upload 24
    What are these as a whole? and what is the arrow pointing to?
    As a whole it is a centriole and the arrow is pointing to one individual microtubule that makes up the centriole. *Usually 9 groups of 3 microtubules each*

    What is this?
    Tight Junction
  13. Image Upload 28
    What is this? and what are the filaments in it that make it different than the others?
    Zonula Adherens - has actin filaments
  14. Image Upload 30
    What is this? and what are the filaments on the outside called?
    Macula adherens - plaque filaments
  15. Image Upload 32
    What is this? what makes it different?
    Gap junction- has INTERLOCKING transmembrane proteins
  16. Image Upload 34
    What is the arrow pointing to?
    transmembrane proteins
  17. Image Upload 36
    What is this?
