Document Summary
Laguna salada de torrevieja in spain: the salty lagoon , water is many times saltier than seawater, pink color comes from trillions of prokaryotes in the domains archaea and bacteria, including archaea in the genus halobacterium. Halobacterium: these archaea have red membrane pigments, some of which capture light energy that is used to drive atp, among the most salt-tolerant organisms on earth. Thrive in salinities that dehydrate and kill other cells. Cell compensates for water lost through osmosis by pumping potassium ions in to the cell until the ionic concentration inside the cell matches the concentration outside. 27. 1: structural and functional adaptations contribute to prokaryotic success. Prokaryotes: first organisms to inhabit earth lived. 3. 5 billion years ago: most are unicellular; some species remain attached to each other after cell division, typically have diameters of. 0. 5-5micrometers: have a variety of shapes, well organized, achieving all of an organism"s life functions within a single cell.
