Microscopic anatomy
The study that uses microscopes to see the minute details of organ parts is called microscopic anatomy.
Microscopic anatomy is the study of cells, tissues and organs of the body that are too small to been seen with the naked eye. Microscopic anatomy usually involves using special staining techniques, combined with electron or light microscope. The use of stains helps to improve colors so that the cells can be more easily identified when they are examined.
Heterocyst-forming cyanobacteria differentiate highly specialized cells to provide fixed nitrogen to the vegetative cells in a filament. In the presence of a source of combined nitrogen such as nitrate or ammonium, Anabaena PCC 7120 grows as long filaments containing hundreds of photosynthetic vegetative cells.
Endospore staining is used to stain the spore which reside inside the microorganisms, and unlike the exospores, are not present outside the microbial cells. The endospore stain penetrates the microbial cells, and then stain the endospore.
