3. Cell membrane Smooth Endoplasmic Reticulum mitochondria microtubules Rough Endoplasmic Reticulum Ribosomes Golgi Apparatus Nucleus Lysosome Nucleolus

4. Nucleus This part is the storage of DNA and all other genetic material, it also functions as a ‘brain’ for the cell.

5. Cell Membrane The part of the cell that controls what nutrients enter and exit the cells. This cell part encompasses and encloses all other parts of the cell. Pale blue indicates the Cell Membrane

6. Rough ER The dark blue part is the Rough ER Rough Endoplasmic Reticulum has ribosomes attached to its membrane Rough Endoplasmic Reticulum transports materials through the cell and produces proteins

7. Smooth ER Smooth Endoplasmic Reticulum does not have ribosomes on it. Smooth Endoplasmic Reticulum transports materials through the cell and produces enzymes and digests fats and membrane proteins

8. Mitochondria Double membrane organelle. The First membrane is folded inside of the second. Mitochondria convert energy into ATP for the cell

9. Ribosomes RNA-Rich organelles that are the site of protein synthesis

10. Lysosome Digests cell parts that have become dysfunctional. Breaks down food molecules.

11. Microtubules Microtubules main function is to structure and support the cell.

12. Golgi Apparatus This part packages proteins and carbohydrates to be exported from the cell

13. Nucleolus Transcribe RNA and assemble it within the cell

16. Which part of the cell provides ATP from converted energy? A. The Cell Membrane The Cell Membrane B. The Golgi Apparatus The Golgi Apparatus C. The Mitochondria The Mitochondria What part of the cell is this? A. The Mitochondria The Mitochondria B. Smooth ER Smooth ER C. The Golgi Apparatus The Golgi Apparatus What part of the cell can help breakdown food particles? A.LysosomesLysosomes B.RibosomesRibosomes C.Endoplasmic ReticulumEndoplasmic Reticulum The microtubules structure and support the cell. True False What part of the cell is this? A.NucleolusNucleolus B.RibosomeRibosome C.Smooth ERSmooth ER What other cell part makes the endoplasmic reticulum smooth or hard? A.RibosomesRibosomes B.LysomoesLysomoes C.MitochondriaMitochondria Which part of the cell encloses all other cell parts?
