  1. Cell Organelles Pages 20-21

  2. Organelles • Structures inside of cells that perform different cell activities! • Also known as “little or tiny” organs

  3. Nucleus (Nuclei) • Known as the “control center” of the cell • Operates like our brain • Contains DNA instructions(our genetic information). • Give the instructions for protein synthesis NUCLEUS

  4. Mitochondria (Mitochondrion) • Known as the “powerhouse” of the cell • This is the place where energy(ATP)is made • Contain folds called cristae • If you increase the surface area (# of folds), MORE energy is made

  5. Vacuole • Stores waste (mostly water) • Larger in plant cells than animal cells • Plants need to absorb excess water • Larger vacuole = more water • Smaller vacuole = less water

  6. Chloroplast • ONLYPlant Cells have chloroplast • This is the place where photosynthesis takes place – makes glucose! • Remember photosynthesis is the reaction plants use to make their own food

  7. Ribosome • Site of PROTEIN PRODUCTION • RNA travels to ribosomes to make proteins • They look like small dots

  8. Cilia & Flagella • Help the cell move • Cilia = short, hair-like structure • Flagella = long, whip-like structure

  9. Cytoplasm • Gel-like substance throughout the cell that holds the organelles in place

  10. Cell Wall • ONLYPlant Cells have a cell wall • Located on the outside of the plasma membrane • Provides structure and support

  11. Plasma Membrane • Can be called semi-permeable OR selective • Allows certain material into and out of the cell • Known as the “gate-keeper” of the cell • Responsible for maintaining a stable, internal environment (HOMEOSTASIS)

  12. Plasma Membrane • Also known as cell membrane & phospholipid bilayer • Made of many phospholipids • Heads: Hydrophilic (water loving) • Tails: Hydrophobic (water fearing)

  13. Plasma Membrane • Proteins are found within the plasma membrane • Channel Proteins  allow materials to pass through • Receptor Proteins  allows the cell to communicate with other cells

  14. Plasma Membrane

  15. Cell-fies Instructions: Draw and Color illustrations on the front. On the back write the name of the organelle and provide the function of each Plasma Membrane Ribosomes Nucleus Vacuole Mitochondria Chloroplast

  17. Organelle How can I remember it? Plasma Membrane Members only can come and go. Cell Wall I'm a brick wall. Cytoplasm Sail through my plasma. Nucleus I'm the control center. Mitochondria I am a "mighty" power house. Vacuole I'll store anything,(Hint: Vacuum Bags) Chloroplast Make me something sweet to eat Ribosomes I make “some” nice protein
