  1. Cell Organelles S7L2: Cell Structure and Function

  2. CELL ORGANELLES • Organelles: Structures within a cell with special functions.

  3. Cell Wall (School Walls) • Cell Wall- Strong, rigid wall that protects the cell and gives it shape. • Plants cells have cell walls; Animal cells do not.

  4. Cell Membrane (Building Doors) • The outer covering of a cell. • Used for protection and support. • Lets good stuff in; keeps bad stuff out.

  5. Cytoplasm (Air) • A gel-like substance found inside the cell. • Used to support the organelles.

  6. Nucleus (Main Office) • Regulates and controls all the activities within a cell. • Contains chromosomes which contain DNA- hereditary material

  7. Nuclear Membrane • Covers and protects the nucleus. • Controls what enters or leaves the nucleus.

  8. Chloroplast (Cafeteria) • Green organelle that makes sugar for plants. • Chloroplast is used in photosynthesis. • Contain chlorophyll- Green pigment that captures the sun’s light. • Plants contain chloroplast; animal cells do not.

  9. Mitochondria (Generator) • Bean or Rod-shaped organelle that produces ATP (provides energy) by performing cellular respiration. • The POWERHOUSE of the cell!

  10. Endoplasmic Reticulum (ER)(Hallways) • A network of passages used to move proteins and other materials throughout the cell. • Comes in two types: Rough (has ribosomes) and Smooth (does not have ribosomes)

  11. Ribosomes (Workers) • Tiny organelles that are used to make proteins. • Some float throughout the cytoplasm, others are stuck to the rough endoplasmic reticulum.

  12. Golgi Body/Complex/Apparatus(Packaging Center/Mail Room) • This large organelle modifies and packages proteins. • It is the “Packaging” center for the cell.

  13. Vacuoles (Lockers) • Organelles that are used for storage. • Vacuoles store food, water and waste.

  14. Lysosomes(Custodians) • Small round organelles that contain digestive chemicals. • Used to break down food, waste and dying organelles.

  15. Nucleus Chloroplast Mitochondria Rough ER Organelles Vacuoles Smooth ER Lysosomes Ribosomes Golgi Body

  16. From Cell to Organism • Groups of cells combine to form tissues. • Groups of tissue combine to form organs.

  17. From Cell to Organism (Cont) • Groups of organs combine to form organ systems. • Groups of organ systems combine to form an organism.

  18. Cells Tissues Organs Organ Systems Organisms
