BIOLOGY 1107 5. Cyanobacteria However, are aquatic and so photosynthetic, they are not they are often called blue-green algae. a at al truly bacteria. Their association with algae They are ability erium was able take up residence within karyotic cell lost its to live independently, a and even which is a process called endosymbiosis A. Make a wet mount of Anabaena cyanobacteria fi at 400x and draw a representative specimen. Total mag B. Estimate the size of a single Anabaena cell using techniques used in the microscopy lab. You may refer back to that lab for the basic measurements. 1. Measure the entire FOV er at low magnification (40x: mm 2. Calculate Fow diameter at high magnification (400x: 3. Estimate the of Fov diameter occupied by 20 Anabaena cells in a chain a 400x: 4. Calculate the length of the chain: mm 5. Divide the length of the chain by the number of cells in it (20) to find the size of 1 cell. The size of 1 Anabaena cell is approximately: mm which is wm

Solution

1.Measure the entire FOV diametre at low magnification (40x) is 4.0mm(4.45)

2. Fov diameter at high magnification (400x) is 0.4mm (0.45).
