Presentation Transcript

  1. Cell Organelles “Inside a Cell”

  2. Cell Membrane Semi-permeable (phospholipidbilayer) Allows molecules to pass in and out of cell

  3. Cytoskeleton “Cyto” = cell Provides structure Helps organize cell division

  4. Mitochondrion Powerhouse Generates the cell’s energy (cellular respiration) Has circular DNA

  5. Nucleus Control center Directs the cell’s activities Stores and protects DNA

  6. Endoplasmic Reticulum (ER) Passageway for proteins Where chemical reactions occur Rough and smooth

  7. Golgi Apparatus Packages proteins, tags them, and sends them off A package is a vesicle

  8. Lysosome “Lyso” = break down Contains digestive enzymes Breaks down food and old cell parts “Clean-up crew”

  9. Vacuole Storage - stores nutrients and water Provides pressure Large in plant cells

  10. Chloroplast ‘Chloro” = green Photosynthesis occurs here Converts energy from the sun into sugar

  11. Cell Wall Protection – protects the cell from injury Provides support

  12. Ribosomes Produce proteins Found in cytoplasm or attached to ER (Rough)

  13. Cytoplasm Gel-like fluid Found throughout the cell

  14. Nucleolus Where ribosomes are made
