In the light of recent classification of living organisms into three domains of life (bacteria, archaea and eukarya), which one of the following statements is true about archaea?
1 Archaea completely differ from both prokaryotes and eukaryotes
2 Archaea completely differ from prokaryotes
3 Archaea resemble eukarya in all respects
4 Archaea have some novel features that are absent in other prokaryotes and eukaryotes
Explanation:
Archea belong to the domain Archaea and are single celled, prokaryotic organisms that do not have membrane bound organelles and are distinct from both bacteria and eukaryotes. One unique character of Archaea is their ability to thrive in extreme environmental conditions that would kill other life forms. - The group contains methanogens that can produce methane gas. The DNA of these organisms is generally present in a relaxed state or as positively coiled. The cell wall of these organisms does not contain lipids, peptidoglycan etc.

Which one of the following statements about mycoplasma is wrong?
1 They cause diseases in plants
2 They are also called PPLO
3 They are pleomorphic
4 They are sensitive to penicillin
Explanation:
Mycoplsma is the free living and the simplest of the prokaryotes. They were found in the pleural fluid of the animals who were suffering from pleuropneumonia and they are called PPLO which stands for pleuropneumonia like organism. MYCOPLASMA

Bacteria differ from plants in that they do not have
1 DNA
2 RNA
3 cell wall
4 a well define nucleus
Explanation:
Bacteria are prokaryote unicellular organisms. They lack membrane bounded cell organelles and a well-defined nucleus. Plants are eukaryotes multicellular organisms. They are eukaryote. They have organelles and well defined nucleus. Both plant and bacteria have cell wall and DNA and RNA but the cell wall of plant cell made up of cellulose and bacteria cell wall is made up of murein. - In plant cell wall, DNA found in multiple chromosomes while in bacterial cell wall DNA is in a single circular ring.
