The cytoplasm is the soup the organelle float in. Cytoplasm is not organelle, but surrounds the orgamelle.

Purpose

They cytoplasm is everything in the cell that is not an organelle.

Function

This contains many of the proteins, molecules, and important substances that the cell needs, as well as keeping the organelles separate. It is similar to air for us; it has many essential ingredients for continued existence; it provides a medium in which the organelles can exist (living in a vacuum is not very easy), and pretty much fills up space.

Location

Inside the cell wall and cell membrane, around the all the organelles.
