Full Name – 2021 3/30/2012 Homeroom Freedom is not free. Aims: •  SWBAT create and label cell diagrams in order to compare and contrast plant and animal cells. Do Now: 1. Are trees made out of cells? Why or why not? 2. Are rocks made out of cells? Why or why not? 3. Define vacuole: Spray on skin graft Aim: SWBAT create and label cell diagrams in order to compare and contrast plant and animal cells. Agenda: Entrance Procedures (5 min) Plants vs. Animals (20 min) Labeling Cell Diagrams (10 min) Test your knowledge! (15 min) Closing (5 min) Do Now: 1. Are trees made out of cells? Why or why not? Yes, trees are made out of cells because they’re alive. 2. Are rocks made out of cells? Why or why not? No, rocks are not made out of cells because they’ve never been alive. 3. Define vacuole: The storage space of the cell. Hook What’s the difference between plants and animals? Plants vs. Animals Plants Cell wall Adds structure (like bones) Chloroplasts Photosynthesis Both Animals Cell membrane Lysosomes Keep things in/out Garbage disposal (full of acid) Mitochondria Cell’s powerhouse Nucleus Cell’s control center Ribosomes Make proteins Vacuoles Storage space Cytoplasm Cellular jello Cell Diagrams: Animals Plants Cytoplasm Cytoplasm Cell membrane Lysosome Vacuole Nucleus Nucleus Ribosomes Chloroplast Vacuole Ribosomes Mitochondrion Mitochondrion Use your notes on the previous page to label the cell diagrams. Cell membrane Cell Wall Cell Diagrams -­‐ Plants Cell Wall Use your notes on the previous page to label Chloroplast the cell diagrams. Test your knowledge! 1) Why do both plants and animals have nucleuses? 2) What’s DNA used for? 3) Why do you think only plants have cell walls? 4) What’s the difference between a cell membrane and a cell wall? 5) What’s one thing a cell could store in a vacuole? 6) What’s the difference between mitochondria and chloroplasts? 7) Do plants breathe? Use the words mitochondria and chloroplasts in your answer. 8) What do scientists think mitochondria used to be? Bonus: Why do they think that? Extension If a saltwater fish is placed in an environment that does not contain the excess levels of salt outside, such as in freshwater, their natural inclination to pull in water and dispel all salt from that water will result in the fish exploding with water that is not being removed from them by their environment. Freshwater fish, on the other hand, are subjected to a reverse effect. The salt levels inside their bodies are higher than the surrounding water outside because that water is constantly being drawn inward by the salt content in their system. Freshwater fish do not drink water as a result. If placed in a saltwater environment, they would literally [shrivel up as most of the water in their bodies drain into the ocean].
