Cholesterol is a steroid that plays a key role in the structure and function of cell membranes. It helps maintain membrane fluidity and stability, and is also a precursor for the synthesis of other important molecules such as steroid hormones.
Cholesterol makes up an important part of cell membrane.

The main 'component' of the Cell's membranes are fatty acids, also known as lipids.

The endoplasmic reticulum makes membranes and processes proteins in a cell. There are two types: rough endoplasmic reticulum (with ribosomes attached for protein synthesis) and smooth endoplasmic reticulum (involved in lipid synthesis and detoxification).

Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
I love that fact that you're cheating in Biology.
