Document Summary
The microscope operate the compound light microscope and the dissecing microscope to examine specimens; 6. focus specimen using the coarse focusing knob. 7. raise condenser and open iris diaphragm, move specimen aside. 8. lower condenser unil paper on light source is in focus: adcust iris diaphragm by removing eyepiece and closing the diaphragm unil. Of the ield is illuminated: replace specimen, and ine focus, centre specimen, posiion high power obcecive, adcust iris diaphragm, ine focus apply a scale to your drawings; esimate the size of microscopic obcects; Cell structure describe the structures and funcions of a cell; Protein channels: passive = relies on concentraion or ionic gradient, acive = requires energy in the form of atp. Processes and packages proteins such as carbs or lipids. Has own dna (suggests it was originally a single organism) Theory that it was originally a bacteria which was engulfed explain surface area to volume raios in relaion to cells;
