1) cell membrane: protects and separates the cell from other cells in the environment, controls what enters and leaves the cell
2) mitochondria: generate most of the chemical energy needed to power the cell's biochemical reactions. (referred to as powerhouses)
3) Smooth ER: synthesizes lipids, phospholipids as in plasma membranes, and steroids
4) rough ER: produce proteins for the rest of the cell to function
5) nucleus: store the cell's DNA, maintain its integrity, and facilitate its transcription and replication.
6) cytoplasm: provides a platform upon which other organelles can operate within the cell.
7) Vacuole: help sequester waste products
8) lysosomes: They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
9) ribosomes: the site of protein synthesis in the cell.
10) Golgi apparatus: Golgi apparatus prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell.
