Eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Taya2010 [7]

Answer:

primary; counter; Gram-positive; Gram-negative

Explanation:

The illustration is about the <u>Gram-staining procedure.</u>

<em>The procedure is used to distinguish between the bacteria that have a thick cell wall capable of retaining the color of a dye (Gram-positive) or otherwise (Gram-negative). </em>

A smear of the bacterium to be tested is heat-fixed to a clean glass slide after which a suitable primary stain is added, allowed to stay for a few seconds, and rinsed. A mordant is then added, rinsed before a counter-stain is added, and also rinsed. The slide is then allowed to drain off water and then viewed under the microscope using the oil immersion. Gram-positive bacteria will appear blue or purple, taking up the color of the stain while Gram-negative bacteria will appear red under the microscope.
