THE EMINENT D

OMAIN

DOMAIN ARCHAEA-1 cell prokaryote -Have different cell walls than bacteria-Lack peptidoglycan cell walls-Reproduce asexually-Live in extreme environments-Some eat by producing bacteriorhodopsin, which allows them to convert sunlight into ATP, which provides energy. Genus Oxytricha Pediastrum Duplex

DOMAIN BACTERIA-1 cell prokaryote -Reproduce by binary fission -Have peptidoglycan cell walls-Break down food products in people-Have been present for ¾ of Earth’s life Cyanobacteria Escherchia Coli

WHY ARE WE IMPORTANT?-Without prokaryotes, you wouldn’t be able to digest -Helps with nitrogen fixation, without which life would be impossible.-Make nutrients for soil that allow things to grow.-Beginning of the food chain

WHAT HAPPENS IF EARTH BECOMES INHABITABLE?

Prokaryotes like Archaea will still be on the ocean floor, still alive and thriving.
