8. II. Cell Control D. ___________ 1. Clear, gelatinous fluid that contains all of the organelles except the ___________

9. Let’s continue to follow the trail of the protein!!

10. III. Assembly, Transport & Storage A._________________ (ER) 1. Rough ER—Ribosomes make proteins here 2. Smooth ER—The proteins undergo chemical reactions a. ________ & storage of lipids

11. III. Assembly, Transport & Storage 3. The ER is a highly _____ membrane a. Allows for a lot of work to be done in a small amount of space

12. III. Assembly, Transport & Storage B. ____________________ 1. Sorts proteins into packages called vesicles (A.K.A. The Post Office) 2. Sends _________ to the appropriate destination in the cell 4. Looks like a pancake stack & syrup drops (vesicles)

13. III. Assembly, Transport & Storage C. ___________ 1. Temporary storage of materials in the cell a. food b. __________ c. water d. ________________

14. III. Assembly, Transport & Storage 2. Animal cells usually do NOT have _______. If so, they are very small. 3. Plant cells usually have one ______ vacuole.

15. III. Assembly, Transport & Storage D. __________ 1. Digest worn out cell parts, food particles, viruses, etc. 2. Lysosomes contain enzymes a. The membrane around the lysosome protects the rest of the cell from being __________.

16. III. Assembly, Transport & Storage b. The lysosome _____- with a vacuole and releases the enzymes into the vacuole to digest its contents.

17. Where does a cell get the energy to make these proteins??? Stay tuned to find out…

18. IV. Energy Transformers A.Chloroplasts 1. Capture ______ and convert it to chemical energy (food) 2. Found mostly in ____ cells

19. IV. Energy Transformers 3. Type of _______ a. a group of plant organelles used for _______ of food or pigments b. Chloroplasts store the green pigment chlorophyll 1) Traps the sunlight needed for photosynthesis

20. IV. Energy Transformers B. _____________ 1. Breaks down the _____ into a form of energy that the cell can use (ATP) a. This process is called _____________________ 2. Folded membranes allow for a lot of work to be done in a small space a. Looks like kidney bean with accordion folds.

21. IV. Energy Transformers 3. The number of mitochondria depends on the ______ of the particular cell a. Liver cell & muscle cells have ________ mitocondria b. Cellular respiration occurs here

22. Can cells move??? You bet! Here’s how…

23. V. Support & Locomotion A.______________ 1. Support structure of the cell a. Organelles don’t just float around in the cell! b. _________ (hollow) and microfilaments (solid) make up a framework for cell shape and movement of materials

24. V. Support & Locomotion B. _________ 1. Short, hair-like projections that cover the cell surface. 2. Move like the oars of a row boat to propel the cell forward or bring things to the cell.

25. V. Support & Locomotion C. _________ 1. Long tail-like projections on the cell 2. Usually a cell only has one or two flagella 3. Makes a ________ motion
