  1. Which type of cell contains organelles? • Prokaryotic • Eukaryotic • Both • Depends

  2. Remember! Video Eukaryotic cells are like a factory. WHY? Eukaryotic cells contain subunits called organelles that help the cell to perform specific functions!

  3. Cell Organelles

  4. What do you all ready know about organelles?

  5. Cell Membrane (Plasma Membrane) • Structure: • Barrier that surrounds all cells • Made of a double layer (a bilayer) of phospholipids • Function: • Semipermeable: selectively permeable (some things can pass, but some things cannot) • Maintains homeostasis (balance)

  6. Mitochondria • Structure: • 2 membranes (outer & inner) • Function: • The power house: produces energy for the cell Active cells, like muscle cells, will have many mitochondria!

  7. Chloroplasts • Structure: • Found only in plant cells! • Contain chlorophyll (greenish) • Function: • Converts light energy (from the sun) to chemical energy via photosynthesis

  8. Nucleus • Structure: • Only in eukaryotic cells! • Contains the DNA • Function: • The control center: contains the genetic material which chemically directs all of the cell’s activities

  9. Smooth Endoplasmic Reticulum (ER) • Transition area where chemicals that the cell has made are stored for transportation to other parts of the cell

  10. Rough Endoplasmic Reticulum (ER) • Structure: • Has ribosomes on the surface (makes it look rough) to assemble proteins • Function: • Transports chemicals between & within cells

  11. Ribosomes • Structure: • Some are found on the surface of the ER & some within the cytoplasm of the cell • Function: • involved in protein synthesis

  12. Vacuole • Structure: • Plant cells generally have 1 large vacuole, while animal cells have many smaller vacuoles • Function: • Storage (like excess water)

  13. Golgi Apparatus • Function: • Shipping & receiving department of the cell • Modify, sort, & package materials from the ER for storage in the cell or release from the cell

  14. Cytoskeleton • Function: • Helps to maintain the cell’s shape • Acts as both a skeleton & a muscle

  15. Lysosome • Function: • The clean up crew: contains digestive enzymes to break down large molecules & cell parts

  16. Cell Wall • Structure: • Mainly plant cells & prokaryotic cells, NOT animal cells! • Outside of the cell membrane • Rigid • Function: • Gives cells a very defined (or definite) shape

  17. Flagella Cilia Structure: Small, hair-like Made of microtubules (cytoskeleton) Function: Movement • Structure: • Long, whip-like • Made of microtubules (cytoskeleton) • Function: • Swimming

  18. Centrioles • Structure: • Cylindrical arrangement of microtubules (cytoskeleton) found perpendicular to each other • Function: • Aid in animal cell division (where spindle fibers attach during mitosis & meiosis)

  19. Animal vs. Plant Cells What are some similarities & differences between animal & plant cells?
