33. Levels of Organization

34. Nucleus (Boss) Nucleus - contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules

35. Organelles (Little Organs) Endoplasmic Reticulum (ER) - internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified Golgi Apparatus- stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum Vesicle- used to transport raw material into the cell to be broken down into smaller usable parts AND MANY MORE (Chapter 7-2 in Textbook)!!!! Which organelles do you think would be the most common in muscle cells? This “power house” converts the chemical energy stored in food into compounds that are more convenient for the cell to use Levels of Organization

46. Jump In: Osmosis What kind of membrane is this? Which direction will the water flow? Which cell is in an isotonic, a hypertonic and a hypotonic solution? 1. 2. 3. Cell Limitations (cont.)

50. Jump In: Which molecule(s) do you think will diffuse across the Plasma Membrane most quickly? Why? What kind(s) of transport will be used? Which molecules do you think will diffuse across the Plasma Membrane least quickly? Why? What kind(s) of transport will be used? What is the relationship between molecule size and the rate of diffusion? The smaller the molecule, the faster it will diffuse and most likely passive transport is used.
