1 3.2 Cell Organelles Eukaryotic Cell: Organelles pg 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

2 3.2 Cell Organelles Eukaryotic Cell: Organelles pg 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 3.2 Cell Organelles Mitochondria Convert molecules from the food you eat into usable energy Powerhouse of the cell Rough E.R. Example

4 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? 2.1 Atoms, Ions, and Molecules Compare: What similarities do mitochondria and chloroplasts share? 3.2 Cell Organelles Key Concept: Eukaryotic Cells share many similarities

5 3.2 Cell Organelles KEY CONCEPT Eukaryotic cells share many similarities. Plant Cell Animal Cell Can you find some similarities????

6 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

7 3.2 Cell Organelles Like your body, eukaryotic cells are highly organized structures.

8 3.2 Cell Organelles Skin: Receives sensory information (touch) Protects Intestines: Digest food Kidneys: Filter waste Bones: Protect and support other organs

9 3.2 Cell Organelles The Living Cell Video

10 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?

11 3.2 Cell Organelles The cytoskeleton is made of small protein subunits that form long threads, or fibers, that crisscross the ENTIRE cell.

12 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?

13 3.2 Cell Organelles * The nucleus stores and protects genetic information or DNA (deoxyribonucleic acid). – –Contains instructions to make proteins

14 3.2 Cell Organelles Nucleus Video

15 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

16 3.2 Cell Organelles – –* Smooth endoplasmic reticulum Makes lipids

17 3.2 Cell Organelles * Golgi apparatus- processes, sorts, and delivers proteins to different parts of the cell Ex: like a post office

18 3.2 Cell Organelles Vesicles transport materials from place to place within the cell Ex: Mailman/UPS

19 3.2 Cell Organelles * Mitochondria supply energy to the cell. – –convert the molecules you eat into usable energy – –Where cellular respiration occurs

20 3.2 Cell Organelles Centrioles help divide DNA between splitting animal cells (mitosis and meiosis) *only in animal cells

21 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

22 3.2 Cell Organelles Lysosomes contain enzymes. –They defend the cell from invading bacteria and viruses – –Break down damaged or worn out cell parts

23 3.2 Cell Organelles A cell wall gives shape to the cell and provides protection –support the entire organism. *Only in plants

24 3.2 Cell Organelles * Chloroplasts convert solar energy to chemical energy. They carry out photosynthesis *Only in plants

25 3.2 Cell Organelles Animal Vs. Plant Eukaryotic Cells Video (3 videos) Bottom ½ of pg. 26 Plant Cells Animal Cells
