GIZMO STUDENT EXPLORATION: CELL TYPES TEST QUESTIONS WITH CORRECT VERIFIED ANSWERS 2023/2024 RATED A+, BEST EXAM SOLUTION FOR BIOLOGY Gizmo Student Exploration: Cell Types Name: Vocabulary: ATP, bacteria, carbon dioxide (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. You know if something is alive if it has cells or DNA 2. Humans, plants and mushrooms are all alive. What do these organisms have in common? They each have cells or DNA 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?I believe that I see the the skin of the elodea leaf 2. Select the 400x magnification. If necessary, adjust the fine focus. Now, what do you see? After the 400x magnification, I believe that I see the cells of the leaf . 3. The individual chambers you see are cells, the smallest functional unit of an organism. 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. Activity A: Observing cells GIZMO STUDENT EXPLORATION: CELL TYPES TEST QUESTIONS WITH CORRECT VERIFIED ANSWERS 2023/2024 RATED A+, BEST EXAM SOLUTION FOR BIOLOGY 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? 1. Match : Read about each microscope part. Match the description to the part on the diagram. B Stage: Platform where a slide is placed. A Eye piece: Lens at the top of the microscope that the user looks though. This lens most commonly magnifies a sample by 10x. C Coarse focus knob: Large knob that moves the stage up and down to focus the sample. D Fine focus knob: Small knob that moves the stage over a short distance to refine the focus. E Objective lens: A second lens that further magnifies the sample. Microscopes usually have several objective lenses with different magnifications. The total magnification is the product of the eyepiece magnification and the objective lens magnification. F Slide: A rectangular piece of glass upon which a sample is mounted for viewing under a microscope. 2. Manipulate : With 40x selected, use the Coarse and Fine focus sliders to focus on the sample. Then, choose 400x and focus on the sample using the Fine focus slider. A. Which focus knob is easier to use at 40x? coarse focus 400x? fine focus B. Turn on Show labels. What structures can you see in human skin cells? I see nucleus, cytoplasm, and a cell membrane GIZMO STUDENT EXPLORATION: CELL TYPES TEST QUESTIONS WITH CORRECT VERIFIED ANSWERS 2023/2024 RATED A+, BEST EXAM SOLUTION FOR BIOLOGY 5. Compare : Look at the Sand/silt sample under the microscope. Get the Gizmo ready: On the LANDSCAPE tab, click on the woman’s head to choose the human neuron sample. Activity B: Specialized cells GIZMO STUDENT EXPLORATION: CELL TYPES TEST QUESTIONS WITH CORRECT VERIFIED ANSWERS 2023/2024 RATED A+, BEST EXAM SOLUTION FOR BIOLOGY A. Turn on Show labels. Does sand/silt have any internal structures? no B. Do you think sand or silt is alive? Explain. I believe that it is not alive as it does not have any orgenelles. Question: How do a cell’s specialized structures relate to its function? 1. Collect data : Use the microscope to observe the samples listed in the table below. For each sample, estimate the cell size and check off the organelles that are present. If there is no column for an organelle, list it in the Special structure(s) column. Sample Estimated size (μm) Nucleus Cell membrane Cytoplasm Special structure(s) Human neuron 60 um yes yes yes Axon, dendrite Human skin 60 um yes yes yes none Human muscle 80 um yes yes yes striation Human blood 60 um yes yes yes Extra cell membrane and cytoplasm 2. Observe : Select the human skin sample. On the MICROSCOPE tab, choose the 400x magnification, focus on the sample, and turn on Show labels. Click on the Nucleus label. If necessary, adjust the Stage sliders to see the full description. A. What is the function of the nucleus? The nucleus contains the cell’s DNA. The nucleus controls the cell by regulating when genes are turned on and off. B. What is the function of the cytoplasm? A gel-like substance that is composed mostly of water and contains all of the cell’s organelles. C. What is the function of the cell membrane? A lipid bilayer that surrounds and protects the cell, regulating what goes in and out.

Focus the cells at 400x. Turn on Show labels. A. Click on the axon label to read the description. What is its function? A long projection that carries electrical signals away from the cell body
