Transcript Archaebacteria

Archaebacteria
By: Morgan, Kayla and Majid
SAMPLE ORGANISMS!
 Methogens which produce
methane gas
 Extreme thermophiles that thrive in
temperatures up too 110 degrees
celsius
 Extreme Halophiles which are
organisms that live in very salty
water
HABITAT!
 Live in salt water lakes
 Hot water springs
 Animal Guts
 Harsh Environments
 High temperatures
 High acids
CHARACTERISTICS AND
CLASSIFICATION!
 Archaebacteria often life in
environments where most
other organisms cannot
survive distinguishing
themselves from others
 Classified as a phylum
 The cells contain a thick
cytoplasm that contains all of
the molecules and
compounds of metabolism
and nutrition
CORPORAL STRUCTURE!
 Prokaryote
 Cell membrane is a branched chain with linked lipids
 Archae cells only contain a limited amount of




organelles
Unicellular (single celled)
Lack complex organ systems
Radial symmetrical (cutting through central axis at
any point produces two halves that are mirror
images)
Move by flagella
REPRODUCTION AND LIFE
CYCLE!
 Reproduce asexually by binary fission
 Their abundance is largely a result of
their rapid rate of reproduction
 During the process of conjugation,
genetic material is exchanged between
2 bacteria. Lead to genetic
recombination causing that continued
evolution of Archaebacteria
CIRCULATION!
 Archaebacteria don’t have a heart
therefore no circulation whatsoever
 Some use diffusion across the cell
membrane to get the necessary
gases for life in the cell.
DIGESTION!
 Heterotrophs
 Some photosynthesize of chemical,
some break down sulphurs' and
some use hydrogen gas
NERVOUS SYSTEM!
 Archaebacteria do not have brain
 They do have a nervous system
 Respond to light (phototaxis), food
(chemotaxis), temperature
(thermotaxis) and to each other
(conjugation)
RESPIRATION!
+ 02  CO2 + H20 + ATP
 Anaerobic
 CH20
INTERESTING FACTS!
 Archaebacteria were one of the first life
forms to evolve on Earth!
 Archaea are interesting organisms in that
they have genes that are similar to both
bacteria and eukaryotes!
 No species of Archaebacteria is known to
cause infection or disease
