Document Summary

Bacteria are responsible for one of the greatest events in the earth"s history, the. There are 2 major concerns to deal with: No organelles such as mitochondria, chloroplasts, er, or golgi. Classification: domain bacteria (eubacteria) and domain archaea (archaebacteria) A newly discovered deep-sea microbe named loki suggests eukaryotes evolved from archaea rather than representing a separate branch of life. Total of microbial genes is 100x greater than human genome. Our systems are linked together as a superorganism. They produce vitamins we require b. h, and k. they manipulate our immune system. Biofilms can form on solid or liquid surfaces as well as on soft tissue in living organisms, and are typically resistant to conventional methods of disinfection. Attachment irreversible attachment and cell- cell adhesion proliferation . Cell wall and plasma membrane begin to divide. Cross- wall forms completely around divided dna. Donor cell releases dna to recipient cell. Ohage- infected donor cell releases hage to recipient cell.
