					             Chapter 7: Cell Parts and Functions TEST REVIEW!!!

Section 1:
1. Definition of a Cell –
2. Difference between prokaryotic and eukaryotic cells (which ones have membrane
   bound organelles? Which ones are more complex?)
       a. Prokaryote –
       b. Eukaryote –
Section 2:
3. Definition of Organelle –
       a. Types of organelles: know what the structure looks like and its overall
             function and location in the cell.
                 i. Nucleus (and the role of the nucleolus, nuclear envelope and pores)
                ii. Ribosomes (where they can be found: floating in cytoplasm and
                    attached to rough ER)
                iii. Endoplasmic Reticulum/ER (also the difference between rough and
                    smooth ER and each produces)
                iv. Golgi apparatus
                v. Lysosomes
                vi. Vacuoles
                        1. plant cells have a large central vacuole, animal cells do not!
               vii. Mitochondria (energy or powerhouse of the cell!)
                        1. what type of energy does the mitochondria make?
              viii. Chloroplasts (know what type of cell has these)
                        1. what pigment do chloroplasts contain that captures light
                            energy?
                ix. Cell wall – found only in _________ cells!
                x. cell membrane
                        1. what do the terms semipermeable or selectively permeable
                            mean?
                        2. lipid bilayer –
                     3. channel proteins or membrane proteins – what is their
                          function? What do they look like?


Section 3:
4. Cell Membrane:
       a. Homeostasis -
       b. How does the cell membrane help maintain homeostasis?
       c. Passive Transport:
              i. Diffusion
                     1. Concentration gradient –
                     2. Hypertonic –
                     3. Hypotonic -
                     4. Isotonic -
             ii. Osmosis
                     1. How it works
                     2. What happens
             iii. Facilitated Diffusion
       d. Active Transport
              i. With a protein channel
             ii. Endocytosis
             iii. exocytosis
