Answer #1

Answer:(d) monera

  • The kingdom monera includes all prokaryotes.They are basically unicellular but can be mycelial, colonial and filamentous.
  • They contain peptidogycan in cell wall. Naked circular DNA coiled to form nucleoid without association with histones, ribosomes 70s, thylakoids present in photoautotrophs but other membrane bound organelles are absent.
  • Some monerans have the ability to fix nitrogen. Due to presence of these characters in arehaea and nitrogen- fixing organisms they are placed under monera.All others fungi, plantae, protists and animalia are eukaryotic.
