How do you know if something is alive? Describe some of the characteristics of living things. Answer: It is alive if it is composed of cells because it is the fundamental unit of life. The characteristics of living organisms are growth, nutrition, movement, metabolism, reproduction, respiration, irritability 2. Humans, plants and mushrooms are all alive. What do these organisms have in common? Answer: Humans, plants, and mushrooms are composed of cells that possessed homeostasis in which the ability to maintain internal state and regulate the process of energy to survive. 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? Answer: I see green plant cells which are cube shaped. lOMoAR cPSD| 2. Select the 400x magnification. If necessary, adjust the fine focus. Now, what do you see? Answer: I see plant cells with nucleus, cell wall, vacuole, cell membrane, and chloroplast. 3. The individual chambers you see are cells, the smallest functional unit of an organism. lOMoAR cPSD| 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? 400x? Answer: For me, all knobs are easier to use even if it is at 40x or 400x magnification. (Thanks to our professor's instruction I managed to use it accordingly.) B. Turn on Show labels. What structures can you see in human skin cells? Answer: I see nucleus, cytoplasm, and cell membrane.
