Answer :
The main primary advantage of using phase comparison in microscopy is that the living cells can be examined in their natural state without previously being killed and stained with dyes or other heavy metals
Explanation:
The technique has the advantage of making it possible to visualize cell organelles and structures that are invisible in bright fields this makes it easier to distinguish the organelles.
It is suitable for living cells when they are being analyzed in the lab unlike other techniques which require the specimen to be dead, it also good for studying and interpreting thin specimens this is because of its high contrast resolution ability which is the ability to distinguish in detail the distance at which two distinct points of a specimen are located
the phase shifts are invisible but they come visible in brightness variations
