culturing microorganisms

• bacteria reproduce by asexual reproduction, through a process of mitosis. Allows rapid reproduction
• uncontaminated culture of microorganisms are required to investigate the effectiveness or disinfectants and antibiotics
• calculate the area of a bacteria colonie using pi r squared
• microscopes allow us to magnify
• light microscopes have a limited magnification meaning it is hard to see structures inside nucleus
• light microscopes have a limited resolution meaning the image is blurred
• electron microscope have a much greater magnification and resolution than light microscopes
• magnification= size of image/ size of real object
