From Proto-cell to Cell

Tolerance for extreme environment

FIRST CELL

What is the different between these cells?

Some of the differents

~Archaea~3 Domains of Life

3 Domains of Life

LUCA : the Last Universal Common Ancestor

Archaea

Bacteria

(1) Halophiles in salty lakes (2) Thermoproteus in deep-sea hydrothermal vents(3) Sulfolobus in hot sulfur springs (4) Methanococcus in swamps and marshes(5) Acidianus in acidic ponds

EXTREME ENVIRONMENT

http://waynesword.palomar.edu/plsept98.htm

Saltbush scrub and cottonwood trees in Owens Valley, with Owens Salt Lake and the Inyo Range in the distance. The pinkish coloration of the water is caused by high concentrations of Halophilic archaebacteria. Image taken in August 2006.

Owens lake bed along Highway 395 south of Lone Pine with Sierra Nevada in the distance. The salt crust is colored red by dense colonies of Halophilic archaebacteria.
