In cell biology, the cytoplasm is all of the material within a cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. It’s a clear, thick, jelly-like material and organelles found inside cell membrane.
It supports /protects cell organelles
An inner layer of the prokaryotic cells that is rich in protein with gel-like consistency; it houses organelles. 
In eukaryotic cells, it contains the cell contents and the organelles and is gel-like.
