DENDROLOGY

Detailed explanation-1: -Eubacteria are called true bacteria and N-acetylmuramic and they have higher degrees of organization. Archaebacteria are called living fossils and they can survive in extremely harsh (highly acidic, high temperature, methanogenic) environments.

Detailed explanation-2: -During times of extreme conditions not conducive to replication, such as starvation, eubacteria have the ability to become endospores. In this state, the bacteria can tolerate exceedingly high and low temperatures, acidic and basic conditions, and large amounts of radiation. Endospores are extremely hard to kill.

Detailed explanation-3: -Reason: Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.

Detailed explanation-4: -Archaebacteria: Archaebacteria are simple in their organization. Eubacteria: Eubacteria are more complex than archaebacteria. Archaebacteria: Archaebacteria are found in extreme environments. Eubacteria: Eubacteria are found everywhere on earth.
