Here's a breakdown:

* Cell: The basic unit of life.

* Cytoplasm: The jelly-like substance that fills the cell, excluding the nucleus.

* Contents of cytoplasm: This includes various organelles (like mitochondria, ribosomes, endoplasmic reticulum, etc.) as well as the cytosol (the fluid component of the cytoplasm).

So, "cytoplasm" encompasses all the components within the cell membrane except for the nucleus.
