Mor-ganelles Catalyst: What can plants do that animals can’t? What is the function of the cell membrane? If a cell’s nucleus is destroyed, the cell immediately dies. Using the function of the nucleus, explain why. Write in complete sentences! Don’t talk during the Catalyst! Objectives By the end of today, SWBAT… Describe the structure and function of cell organelles related to energy Determine if a eukaryotic cell is a plant or an animal Mitochondria The mitochondria are oval shaped and have lines through them They produce energy (ATP) for the cell itochondria Think-Pair-Share If West Jeff were a cell, what would be the mitochondrion? Chloroplast Chloroplasts are green ovals, and look like they contains stacks of poker chips They allow plants to photosynthesize (use sunlight to make sugar) Only cells found in plant Chloroplast Think-Pair-Share If West Jeff were a cell, what would be the chloroplast? Vacuole Circular storage space for food and water In plant cells, it is gigantic VACUOLE Think-Pair-Share If West Jeff were a cell, what would be the vacuole? Cell Wall The cell wall is found outside the cell membrane in plant cells It holds plant cells in a rectangular shape Only cells found in plant PLANT CELLS ANIMAL CELLS Think-Pair-Share If West Jeff were a cell, what would be the cell wall? Compare and Contrast Organelle Plant cell Animal cell Chloroplast Yes No Cell wall Yes No Vacuole Yes, and huge Rectangle Yes, but small Round Shape Organelle Showdown Choose a partner at your table, and (using the flash cards) quiz him/her Ask difficult questions! Keep track of points First student to earn 20 points wins I want to know who is the organelle master at each table! Whiteboard Practice Please send someone up from your group to grab… One whiteboard for each person One dry-erase marker for each person Behavioral expectations Take the work seriously What is the function of the nucleus? What two organelles that we discussed today are only found in plant cells? This organelle is MUCH larger in plants than animals What is the function of the mitochondria? These types of cells do not have a nucleus Both the chloroplast and mitochondria make energy, but different types. What do each of them produce? What would happen to a cell, if its vacuole were destroyed? This part of the cell is the reason why plants are rectangular in shape Which of these cells is a plant cell? Cell #1: cell membrane, nucleus, cytoplasm, vacuole Cell #2: cell wall, cell membrane, nucleus, chloroplast, cytoplasm Cell #3: cell membrane, cytoplasm, DNA floating in cytoplasm Cell #4: cell membrane, nucleus, cytoplasm, mitochondria, vacuole Which organelle is this arrow pointing to? What is its function? Which organelle is this arrow pointing to? What is its function? Which organelle is this arrow pointing to? What is its function? Plant cell or animal cell? Plant cell or animal cell? Independent Practice Begin on the homework Exit Questions Describe at least TWO differences between plant and animal cells What is the function of the chloroplasts? Which organelle produces ATP? Write in complete sentences! Don’t talk during the Exit Question!
