NEET BIOLOGY

Detailed explanation-1: -They contain 70S ribosomes. The DNA is naked and is not bound by a nuclear membrane. It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, centrosome, etc. They reproduce asexually by binary fission or budding.

Detailed explanation-2: -They are generally unicellular. A membrane-bound nucleus is absent. Double-stranded DNA is suspended in the cytoplasm, known as a nucleoid. Membrane-bound organelles like mitochondria, endoplasmic reticulum, etc.

Detailed explanation-3: -Kingdom-Monera: It comprises unicellular, prokaryotic organisms, having no well-defined nucleus and no organelles.

Detailed explanation-4: -moneran, any of the prokaryotes constituting the two domains Bacteria and Archaea. The monerans are distinct from eukaryotic organisms because of the structure and chemistry of their cells. As prokaryotes, they lack the definite nucleus and membrane-bound organelles (specialized cellular parts) of eukaryotic cells.

Detailed explanation-5: -Monera and Protista contain the two least organized organisms on earth. Monera consists of unicellular prokaryotes. Protista consist of both unicellular and multicellular eukaryotes. Archaebacteria, cyanobacteria and eubacteria are the three types of monerans.
