QX3 Digital Image Gallery
Transmitted Brightfield Illumination
Generalized Plant Cell
The digital images below are typical of those found in plant cells. Thin sections of plants are often stained with a quadruple stain containing the following ingredients: safranin O stains nuclei, chromosomes, lignified and cutinized cell wall red; fast green stains cytoplasm and cellulose cell walls green; crystal violet stains starch grains purple; and orange G stains acidophilic cytoplasm and cell walls yellow to green.
The transmitted brightfield digital images above were recorded using a QX3 microscope that was modified for auxiliary illumination. This was accomplished by directing a fiber optic light pipe at a quarter-inch hole drilled into the front of the mixing chamber to increase the illumination intensity. The light pipe was aimed at the side of the mixing chamber to avoid directing illuminating the frosted diffusion screen.
