|
Why electron microscopes are able to produce clear image of very small objects that even most powerful light microscopes are able to view? |
The shortest wavelength of visible light is 400 nm/.4um Viruses and objects are smaller than the wavelength of light Light does not bounce off objects smaller than its wavelength Resolution of light microscope is half the wavelength of light /.2um Electrons have a smaller wavelength than light Electrons microscopes produce images using electrons no color Object smaller than .2um are unclear Electrons pass through sounds off spice men Electron microscope resolution it's much higher than light microscopes Electrons pass through sounds off spice men Electron microscope resolution it's much higher than light microscopes

|
Process of binary fission |
Bacteria has a single closed-loop circular naked DNA chromosome Cell elongates/grow Chromosome is a replicate/copied semi conservatively into two identical copies
Division of the cytoplasm Two chromosomes are pulled to the opposite of the cell Division of the cytoplasm Daughter cell produced are genetically identical or identical clone cell |
