GIZMO CELL TYPES | Student Exploration Cell Types | ALL ANSWERS CORRECT

Document Content and Description Below

Student Exploration: Cell Types Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: ATP, bacteria, carbon diox... ide (CO2), cell, cellular respiration, compound light microscope, eukaryote, multicellular, muscle cell, neuron, organelle, photosynthesis, prokaryote, protist, red blood cell, root hair cell, tissue, unicellular, white blood cell Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. How do you know if something is alive? Describe some of the characteristics of living things. 2. Humans, plants and mushrooms are all alive. What do these organisms have in common? Gizmo Warm-up In the Cell Types Gizmo, you will use a light microscope to compare and contrast different samples. On the LANDSCAPE tab, click on the Elodea leaf. (Turn on Show all samples if you can’t find it.) Switch to the MICROSCOPE tab to observe the sample as it would appear under the microscope. By default, this microscope is using 40x magnification. 1. Drag the Coarse focus slider until the sample is focused as well as possible. Then, improve the focus with the Fine focus slider. What do you see? 2. Select the 400x magnification. If necessary, adjust the fine focus. Now, what do you see? The individual chambers you see are cells, the smallest functional unit of an organism. Activity A: Observing cells Get the Gizmo ready: ● On the LANDSCAPE tab, click on the woman’s right arm to choose the Human skin sample. ● Select the MICROSCOPE tab. Introduction: Complex organisms are made up of smaller units, called cells. Most cells are too small to be seen by the naked eye. Microscopes are used to magnify small objects, so here you will use a compound light microscope to observe the cells of different organisms. Question: What are similarities and differences between cells from different organisms? ● There are different type of cells in each organism and they act and have different jobs/functions in each organism. They are similar because cells make up organisms [Show More]
