Organelles Organelles Presentation Transcript

  • LAUNCH
    • Pick two organelles from yesterday, describe their function and draw a quick sketch
  • LAUNCH
    • What are the differences and similarities between a prokaryotic and eukaryotic cell? What are examples of each?
  • Parts of the Cell
  • Plant vs Animal Cells
  •  
  • ANALOGY! Organelles perform the functions of the cell just like different people and places perform the functions of LPS! If the nucleus of a cell is analogous to Ms. Klaffky, the principal, what function do you think the nucleus does?
  • Control Center Holds genetic material Nucleus
  • Nucleus Lily Parenchyma Cell. Note the large nucleus and nucleolus in the center of the cell, mitochondria and plastids in the cytoplasm.
  • Nucleus
    • Function: Control center of the cell, holds genetic information of DNA
    • Found: In all Eukaryotic Cells (both plant and animal cells have nuclei)
    • Analogy: Ms. Klaffky (principal)
  • Power Station Produces Energy Mitochondria Changes chemical energy into food
  • Mitochondria
  • Mitochondria
  • The Cafeteria (MPR) Mitochondria
  • Mitochondria
    • Function: convert chemical energy stored in food into compounds which cell can use for energy
    • Found: In All Eukaryotic Cells in the cytoplasm
    • Analogy: Cafeteria
  • Power Station Produces Energy Chloroplast Changes sunlight into food by photosynthesis
  • Found in Plants Only Chloroplast
  • Chloroplast
  • The Cafeteria (again) Chloroplast
  • INTRACELLULAR TRANSPORT
    • ER
    • Golgi
    • Lysosome
    • Vacuole
  • Makes proteins Ribosome Very small
  • Ribosomes
  • Ribosome
    • Function: makes proteins; where translation occurs
    • Found: In All Eukaryotic Cells; in cytoplasm and on rough endoplasmic reticulum
    • Analogy: Guidance Office, Teachers
  • Pathway to ship proteins Endoplasmic Reticulum
  • Endoplasmic Reticulum
    • Function: Pathway to ship proteins
    • Found: All Eukaryotic Cells in cytoplasm
    • Analogy: Hallway
  • E.R.
  • E.R.
  • Hallways Endoplasmic Reticulum
  • Package and ship out proteins Golgi Apparatus
  •  
  • Golgi Apparatus
    • Function: package and ship out Proteins
    • Found: All Eukaryotic Cells in cytoplasm
    • Analogy: Ms. Rivera and Ms. Aguilar, Office Secretaries
  • Golgi Apparatus
  • Golgi Apparatus
  • Main Office / Ms. Rivera Golgi Apparatus
  • Clean up crew Lysosome
  • Lysosomes
    • Function: cleanup crew of cell – eats old stuff
    • Found: All Eukaryotic Cells in cytoplasm
    • Analogy: Custodians
  • The Custodians Lysosome
  • Lysosome
  • Exit Ticket!
    • On your index card, write your name and number 1-3
    • For each slide that is shown, write down the ‘mystery organelle’ being described.
    • Function: Pathway to ship proteins
    • Found: All Eukaryotic Cells
    • Analogy: Hallway
    1.
    • Function: package and ship out Proteins
    • Found: All Eukaryotic Cells
    • Analogy: Office Secretaries
    2.
    • Function: convert chemical energy stored in food into compounds which cell can use for energy
    • Found: In All Eukaryotic Cells
    • Analogy: Cafeteria
    3.
  • LAUNCH
    • Pick two organelles from yesterday, describe their function and draw a quick sketch
  • Controls what gets in and out of the cell Cell Membrane
  • Cell Membrane
    • Function: allow items in and out
    • Found: All Eukaryotic Cells
    • Analogy: Gates of School
  • Cell Membrane
  • Protects the plant cell Cell Wall
  • Cell Wall
    • Function: rigid wall, shape, keep stuff out
    • Found: PLANTS ONLY!!!
    • Analogy: Walls,
  • Found in Plants Only Cell Wall
  • Cell Wall
  • The fence Cell Wall
  • Plastid
    • Function: store starch & fats, others absorb light energy
    • Found: PLANTS ONLY!!!
    • Analogy: you under breezeway
  • Holds cellular organelles in place Cytoplasm
  • Cytoplasm
    • Function: jelly like stuff between cell membrane and nucleus
    • Found: All Eukaryotic Cells
    • Analogy: The whole school inside the cell wall but not the office
  • The Air Cytoplasm
  • Cytoskeleton
    • Function: gives cell structure to maintain shape and size
    • Found: All Eukaryotic Cells
    • Analogy: Your school schedule
  • Storage of food and water Vacuoles
  • Vacuole
    • Function: store enzymes & metabolic wastes
    • Found: PLANTS ONLY!!! (but a few animal cells too)
    • Analogy: Lockers
  • Huge in plant cells Small in animal cells
  • Plant Cells
  • Vacuole
  • The Lockers Vacuoles
  • Cilia and Flagella
    • Function: assist in movement of cell
    • Found: Many Eukaryotic Cells
    • Analogy: Your feet
  • Animal Cells
