Banded iron formations provide evidence of oxygen in the atmosphere. Banded iron formations are sedimentary rocks composed of alternating thin layers formed of iron oxide minerals, such as magnetite and hematite and silica rich minerals such as, chert and iron silicates. Most geologists agree that banded iron formations were precipitated from sea water when oxygen, produced by cyanobacteria, reacted with iron dissolved in sea water.

The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell. The smooth ER also helps in the detoxification of harmful substances in the cell. Ribosomes- Organelles that help in the synthesis of proteins.
