1. Cell Organelles Eukaryotic Cells

2. Cell Parts Cells – the basic unit of life. Organelles - small structures inside a cell with specific functions.

3. A) Cell Membrane/Plasma Membrane 1.Function: Regulates materials entering and exiting the cell and serves as a boundary from outside environment. 2.Structure: Two layers of phospholipids, proteins Cell membrane

4. B) Cytoplasm 1.Function: All cell contents that lie between the cell membrane and the nucleus. (organelles + cytosol) a. Cytosol = liquid portion/non-organelles. 2.Structure: Made up of fluid and organelles except for nucleus Cytoplasm

5. C) Nucleus 1.Function: Controls most of a cell’s processes and stores DNA. 2.Structure: Membrane bound, contains DNA Nucleus

6. G) Endoplasmic Reticulum Function and Structure: a.Rough ER: A membrane system with ribosomes on its surface where proteins are assembled. b.Smooth ER: A membrane system where lipids are assembled. Rough ER Smooth ER

7. H) Ribosomes 1.Function: Makes proteins. 2.Structure: Small circular organelles Ribosomes Free Ribosomes

8. J) Lysosomes 1.Function: Packets of enzymes that break down materials in a cell. 2.Structure: Small membrane-bound organelles Lysosomes

9. K) Mitochondria 1.Function: Produce energy for the cell – site of cellular respiration. 2.Structure: Double membrane-bound, kidney shaped, contains its own DNA Mitochondria

10. L) Golgi Apparatus 1.Function: Modifies, sorts, and packages proteins. 2.Structure: Pancake-shaped layered organelle Golgi Apparatus

11. M) Cytoskeleton 1.Function: Provide support and structure for the cell. 2.Structure: Microtubules and microfilaments Microfilaments Microtubules

12. P) Chloroplasts (Plants only) 1.Function: site of photosynthesis (converting sun and CO2 into sugar). 2.Structure: Membrane bound organelles that contain chlorophyll Chloroplasts

13. Q) Cell Wall (Plants only) 1.Function: Provides support for the cell and the plant. 2.Structure: Made of cellulose Cell Wall

14. Cell Parts Analogy Create an analogy (besides the city analogy) for the cell and its parts Possible ideas: –Stadium –School –Country –Restaurant –House –Mall –Waterpark

15. Stadium Example: Cell membrane: wall of stadium, gates Cytoplasm: everything inside the stadium. Nucleus: the control room for the stadium. Etc…
