Do you need more or less light when viewing a stained preparation?
More light for stained. Less light for unstained. When viewing unstained material, it is necessary to reduce the amount of light to increase the contrast between the cells and the liquid.
What is the definition of negative staining?
negative staining is when the micro-organism on slide is not stained.. instead the rest of the material on the slide gets stained and the organism stands out prominently unstained.. this occurs because that organism has a thick capsule around it which is non-stainable with that stain.. example is pneumococci staining with India ink.
How can a positive result occur during capsule staining?
Capsules may be revealed by methods such as Maneval's method. This method utilizes negative staining, where the background is stained revealing an unstained structure: the bacterial capsule.
What organelles become more visible after being stained with iodine?

Why are living unstained bacterial preparation more difficult to observe microscopically than stained preparations?
Staining adds contrast making the bacteria easier to see.
What has the author John Preston Langmore written?

Why are living unstained bacterial preparations more difficult to observe?
Living unstained bacterial preparation is more difficult to see than stained preparations because unstained bacteria is transparent . Living bacteria is also very quick and would be hard to see and track without stain.
