Organelles

Organelles

1. Mitochondrion

   • Produces energy (ATP)
     • Aerobic metabolism

2. Rough Endoplasmic Reticulum (with ribosomes)

   • Manufactures protein

3. Golgi Body

   • Packages proteins into vesicles

4. Smooth Endoplasmic Reticulum

   • Metabolises lipids, detoxifies, stores Ca2+

5. Lysosome

   • Contains enzymes for breaking down substances

6. Nucleus

   • contains DNA, and controls protein synthesis
     • Also contains nucleolus which makes the ribosomes
     • Transcription
     • Translation

7. Plasma membrane

   • controls movement of substances into and out of cell
     • Passive Transport
       • Simple Diffusion
       • Facilitated Diffusion
       • osmosis
     • Active Transport
       • Solute Pump
       • Co-Transport/CounterTransport
       • Vesicular transport

8. Cytoskeleton

   • give cell support or make machinery for cell movements
     • Microtubules
       • Form centrioles to help mitosis with spindle or make cilia/flagella
     • Intermediate filaments
       • provide tensile strength to cells
     • Microfilaments
       • involved in cell movement and shape
