Question

What is the purpose of plunging coffee in a plunger???

Answer 1

it defuses the stronger taste, and caffeine out of the grounds.

Answer 2

A French Press is often times called a coffee plunger or cafetière.  It produces a stronger coffee than other coffee *makers*. The coffee grounds remain in direct contact with the water.  The grounds are filtered from the water by a mesh instead of a paper filter so coffee brewed with the French press captures more of the coffee's flavor and essential oils, hence a benefit of the press/plunger over a drip.  ;-)  It does not capture caffeine.
