Document Summary

Pure culture: isolated group of genetically identical cells. Medium: a solution or solid that contains nutrients cells can use to grow and divide. It can be left as a liquid or mixed with a substance to solidify it. 1. turn light intensity to its lowest power: reduces strain on the bulb when it is turned on. 3. use coarse adjustment knob to move stage down to lowest position. 4. place slide on stage, click 4x objective lens into place. Turn light up to mid-power and use stage adjustment knob to position the specimen so like from condenser is shining on it. 6. focus on the slide by lowering the stage with the course and fine adjustment knobs: for small/transparent specimens, focus on the edge of your coverslip and then move slide until you can see the specimen. 7. set interpupillary distance by moving the ocular lens together or apart. 9. rotate the 10x lens into place: use fine focus knob to focus specimen.
