Transcript
Welcome to science! Complete the following tasks: 1. 2. 3. 4. Place last night’s homework on your desk Write tonight’s homework in your Agenda Complete your Table of Contents Number your Do Now and begin! Do Now 1. Cells 2. Eukaryotes 3. Eukaryotic, since they have a nucleus. EU = You! 4. Animal cells can be round (or another shape), while plant cells are generally square 5. Mitochondria is a cell organelle that is the “powerhouse” of the cell and provides energy PLANT CELL ORGANELLES SWBAT analyze the processes carried out by the organelles in plant cells On Monday, we discussed… On Tuesday, we discussed… Yesterday, we discussed… WRITE-PAIR-SHARE List the organelles you learned yesterday that appear in animal cells. Then, circle the ones you think also appear in plant cells. Organelles Organelles that are in both plant and animal cells: Nucleus Nuclear membrane Cytoplasm Cell/plasma membrane Mitochondria Endoplasmic reticulum Golgi Bodies/Apparatus Ribosomes Lysosomes (sometimes) Vacuoles Plant Cell Organelles Plant Cells. Cellulose Cell Wall: a rigid wall structure around the cell that gives the cell a rectangular and structural support Plant Cells. Large Central Vacuole: a large “tank” in the middle of the cell that holds water for long periods of time. WRITE-PAIR-SHARE: Animal cells have vacuoles too, but much smaller. What do you think led to this difference? Plant Cells. Chloroplasts: small organelles in each cell that contain chlorophyll responsible for making energy during photosynthesis WRITE-PAIR-SHARE So, plant cells have mostly the same organelles as animal cells, but also have a few extra organelles (as well as a much, much larger vacuole). Why do you think plant cells need more organelles? PLANT CELLS Plant cells are more complicated and have more organelles than animal cells, since plants have to make their own food (photosynthesis) instead of eating it (like animals) Cell Rap again! https://www.youtube.com/watch?v=zafJKbMPA8 3 Important Facts Complete the bottom box on your notes page to sum up what you think were the most important parts of today’s lesson Partner Practice Complete the sheet labeled “Partner Practice” with your partner at a noise level of 1 Broken Heart Today, you are going to become independent, literally You are playing the role of a plant cell who has decided to breakup with your partner, an animal cell You will be writing an informal letter Use the knowledge of informal writing that you are learning in ELA Use only scientific knowledge we’ve covered No “I’m breaking up with you because you never call!” or “I don’t like the way you were flirting with the prokaryotic cell!” Break Up Letter: An Example Dear Prokaryotic Cell, I know we had a lot of similarities. We both are cells, which is the basic building block of living things. But besides that, we are just too different. I am make up multicellular organisms, and you are just a lonely, single cell. I am complicated and made up of many organelles, like a nucleus, mitochondria, and a cell membrane. You, on the other hand, are just TOO BASIC! Finally, I have a nucleus, and you don’t! Because of these differences I am sorry to tell you that I think we need to break up. I hope you understand. Best, Eukaryotic Cell Break Up Letter They have to include 6 of the following 9 terms/ideas: nucleus chloroplast cell wall cell membrane eukaryote large central vacuole lysosome cell shape photosynthesis LET HIM/HER DOWN EASY, PLEASE!!!
