3. 2 Cell Organelles Eukaryotic Cell: Organelles pg. 73 -79 • Determine the main function of the 12 major organelles in eukaryotic cells • Cell membrane • Cytoskeleton • Nucleus • Endoplasmic Reticulum (Smooth and Rough) • Golgi Apparatus • Vesicles • Mitochondria • Vacuole • Lysosomes (animal) • Centrioles (animal) • Cell Wall (plant) • Chloroplasts (plant) Notes on pg. 26 of INB
3. 2 Cell Organelles Eukaryotic Cell: Organelles pg. 73 -79 1. Determine whether you are going to make a plant or animal cell 2. Draw the outline of your cell on your poster 3. Out of construction paper- construct organelles (using a different color for each type of organelle) 4. Label each organelle 5. Write the function of each type of organelle
3. 2 Cell Organelles Example Rough E. R. Mitochondria • • Convert molecules from the food you eat into usable energy Powerhouse of the cell
3. 2 Cell Organelles Sponge: Set up Cornell Notes on pg. 27 Topic: 3. 2 Cell Organelles Essential Question: Compare: What similarities do mitochondria and chloroplasts share? Cell 2. 1 Atoms, 3. 2 Ions, and Molecules Organelles Compare: What similarities do mitochondria and chloroplasts share? Key Concept: Eukaryotic Cells share many similarities
3. 2 Cell Organelles KEY CONCEPT Eukaryotic cells share many similarities. Plant Cell Animal Cell Can you find some similarities? ?
3. 2 Cell Organelles Main Ideas • Cells have an internal structure • Several organelles are involved in making and processing proteins • Other organelles have various functions • Plant cells have cell walls and chloroplasts STANDARDS • • • 1. e Students know that usable energy is captured from sunlight by chloroplasts and is stored through the synthesis of sugar from carbon dioxide 1. g Students know the role of the mitochondria in making stored chemical-bond energy available to cells by completing the breakdown of glucose to carbon dioxide 1. j Students know how eukaryotic cells are given shape and internal organization by a cytoskeleton or cell wall or both
3. 2 Cell Organelles Like your body, eukaryotic cells are highly organized structures.
3. 2 Cell Organelles • Skin: • Receives sensory information (touch) • Protects • Intestines: • Digest food • Kidneys: • Filter waste • Bones: • Protect and support other organs
3. 2 Cell Organelles The Living Cell Video
3. 2 Cell Organelles • Cell membrane: • Separates interior material from outside environment • Selectively permeable (only certain things can move in and out) How can we compare the cell membrane to our skin?
3. 2 Cell Organelles • The cytoskeleton is made of small protein subunits that form long threads, or fibers, that crisscross the ENTIRE cell.
3. 2 Cell Organelles – provides strength, shape, and support – helps position and transport organelles – assists in cell division How can we compare the Cytoskeleton to our human Skeleton?
3. 2 Cell Organelles • *The nucleus stores and protects genetic information or DNA (deoxyribonucleic acid). – Contains instructions to make proteins
3. 2 Cell Organelles Nucleus Video
3. 2 Cell Organelles There are two types of endoplasmic reticulum. –* Rough endoplasmic reticulum – Have bumps called ribosomes which link amino acids together to form proteins –protein synthesis occurs here
3. 2 Cell Organelles –* Smooth endoplasmic reticulum Makes lipids
3. 2 Cell Organelles * Golgi apparatus- processes, sorts, and delivers proteins to different parts of the cell Ex: like a post office
3. 2 Cell Organelles • Vesicles transport materials from place to place within the cell Ex: Mailman/UPS
3. 2 Cell Organelles • * Mitochondria supply energy to the cell. – convert the molecules you eat into usable energy – Where cellular respiration occurs
3. 2 Cell Organelles Centrioles help divide DNA between splitting animal cells (mitosis and meiosis) *only in animal cells
3. 2 Cell Organelles • Vacuoles are fluid-filled sacs that hold materials needed by the cell (water, food molecules, ions, and enzymes) Animal cell Plant cell
3. 2 Cell Organelles • Lysosomes contain enzymes. – They defend the cell from invading bacteria and viruses – Break down damaged or worn out cell parts
3. 2 Cell Organelles • A cell wall gives shape to the cell and provides protection – support the entire organism. *Only in plants
3. 2 Cell Organelles • * Chloroplasts convert solar energy to chemical energy. They carry out photosynthesis *Only in plants
