We know this based on the presence of stromatolites - fossilized microbial mats consisting of layers of filamentous prokaryotes - and trapped sediment that date back to that time.

The energy released as electrons pass down the gradient between photosystem II and photosystem I is harnessed by the cytochrome b6/f complex to pump protons (H+) against their concentration gradient from the stroma of the chloroplast into the ...

Phycobilins are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast. They occur only in Cyanobacteria and Rhodophyta.
