Archaebacteria

What are they?

- Archaebacteria are a single-celled organism that lacks a nuclei.

- They are very different from other bacteria that are known due to it having a unique protein like cell walls/membranes and distinctive ribosomes.

- Multiple people have thought that the archaebacteria resembled ancient bacteria that first arose in extreme environments.

Where do they live?

Archaebacteria are found in the harshest conditions on Earth.

Examples of their natural habitat can be: volcanic vents in the sea, hot springs, boiling mud, etc.

What do they eat/ get energy?

- Archaebacteria don’t eat anything to survive

- They get nutrients and energy by absorbing certain types of chemicals

- This is because they are considered on being chemosynthetic

Is there anything that can eat archaebacteria?

- Though Archaebacteria can obtain its own food by absorbing nutrients they can still be eaten by other species.

- Mainly fungi and many other bacteria’s can be able to eat archaebacteria.

How do they reproduce?

- Archaebacteria do not reproduce like how mammals reproduce

- They instead reproduce asexually by binary fission, fragmentation, or by budding, which means that they reproduce by dividing in half.

- This causes each and every one of reproduce Archaebacteria to have the same genetic material.

Bacteria and Archaebacteria

Though they can be made out to be pretty similar from one another, they are in fact a lot more different than you think:

- Archaea cannot be able to produce spores unlike bacteria can.

- Archaea cell walls do not contain peptidoglycan as well as different membrane lipid bonding compared to with bacteria.

- Archaeal lipids lack the fatty acids found in bacteria and eukaryotes, but instead have side chains composed of repeating units of isoprene.

Are they heterotrophic or autotrophic?

- Archaebacteria are considered on being heterotrophic

- Due to its ability on living in harsh environments, and being able to absorb organic substance instead of eating food to survive.

Are they heterotrophic or autotrophic?

Are they harmful towards humans?

Archaebacteria are luckily non harmful towards humans, but can be seen as quite a helpful organism inside the human gut by aiding out digesting complex sugars.

Are they harmful towards humans?

Benefits of Archaebacteria

- Some Archaebacteria help humans digest food

- They play a role in the Nitrogen Cycle and Carbon Cycle

- Some Archae are used in sewage treatment

Interesting Facts

- Many of the archaebacteria can survive at a high (over 80 degrees) or very low temperatures.

- They are classified in a separate domain in the three domain system being the three distinct branches of evolution being the: Archaea, Bacteria, and Eukaryota.

- No archean species can do photosynthesis.

Archaean organisms cannot produce spores like bacteria.

- They make up about 20% of all microbial cells in the ocean, especially being common in plankton.
