1. We should already know that BACTERIA are the smallest ________ things.

2. We should already know that BACTERIA are the SMALLEST LIVING things.

3. In addition, they’ve been around for BILLIONS of YEARS!!!!

4. Why are bacteria the MOST SUCCESSFUL LIFE?
They can survive almost anything!

?????hey can survive almost anything!

8. How TOUGH are you?

9. Could you survive in the antarctic?

10. How about NEGATIVE 89.2 degrees Celsius BELOW ZERO?
urp…that’s cold.

11. Ancient bacteria living in frozen glaciers!
The coldest temperature recorded on Earth was recorded at Vostok Station in Russia. With the help of radar, in 1996, a vast sub-glacial lake was discovered nearby.
The ice core samples have proven valuable, and have resulted in the discovery of BACTERIA THAT ARE 400,000 years OLD.

12. Could you survive undersea WITHOUT a major underwater submersible?

13. How about under tremendous pressure at the bottom of an abyss in total darkness surrounded by toxic gas?

14. How about under tremendous pressure at the bottom of an abyss in total darkness surrounded by toxic gas?
Some bacteria can!!!!

15. Cyanobacteria live in all types of water conditions--polluted & otherwise.
They are the smallest phytoplankton.

16. Chemosynthetic bacteria live under great cold & pressure in toxic gas!
Recently discovered in 1977, hydrothermal vents, also known as "black smokers", revolutionized our understanding of life. Until the discovery of these vent systems, all known ecosystems on Earth had photosynthetic organisms at the base of their food chain.
However, this particular type of ecosystem is dependent on chemosynthetic bacteria that generate energy from hydrogen sulfide, the chemical responsible for the smell of rotten eggs.
These chemotrophic (chemical eating) bacteria exist in symbiotic relationships with other members of the ecosystem including mussels and 8 foot long tubeworms.

17. Could you live in a cave?

18. How about a cave in total darkness with acid dripping on your head?
snottites…

19. Snottite bacteria live in total darkness in acid caves…
They are found hanging from the walls and ceilings of toxic sulphur caves (most notably Cueva de Villa Luz in Tabasco, Mexico).
Show exerpt from ORIGINS that show
snottites…

20. How about living in a BOILING HOT CHEMICAL SOUP??

21. These yellow bacteria live in boiling hot chemical soups!
This vast bacterial mat is found in regions around hot springs such as the Grand Prismatic Springs. There are more bacteria alive in one inch of this bacterial mat than there are humans in existence.

22. Why are bacteria the MOST SUCCESSFUL LIFE?
They reproduce VERY quickly.
BINARY FISSION-superfast asexual divide & split
PROkaryote cell means NO NUCLEUS-NO MITOSIS.
They can live in EXTREME conditions!
hey can survive almost anything!

23. Why are bacteria the MOST SUCCESSFUL LIFE?
They reproduce VERY quickly.

24. Remember that there are millions of species of bacteria!

26. Fossils
Stromatolites are structures created by photosynthetic bacteria (prokaryotes). These rounded, bulbous shapes are usually less than 1 meter across and contain fine layering.
Photosynthetic bacteria live on thin mats in shallow water. As they become covered in clay and particles, these bacteria move upwards toward the light they require. This movement leaves behind dead layers, much in the same way that trees leave behind inner wood as they grow. Stromatolites are recognizable because of the “tree ring” structure that records the movement of bacteria.
The earliest known fossils of stromatolites are dated at 3.45 Ga, and come from Western Australia. Ironically, the highly-saline bays of Western Australia are one of the few places in the world today where living stromatolites exist.

27. Stromatolites…bacteria that have been around BILLIONS of years!

So MANY species, for billions of years!
hey can survive almost anything!

30. There are even BACTERIA species that can LIVE JUST on ELECTRICITY.

They can live in EXTREME conditions!
So MANY SPECIES, for BILLIONS of YEARS!
They adapted to LIVE ANYWHERE!

32. They’ve existed on Earth for billions of years!.
Bacteria are the most successful & primitive life on our planet…maybe Mars?
They’ve existed on Earth for billions of years!

33. What do bacteria and plant cells have in common that our animal cells don’t?
