NEET BIOLOGY

Detailed explanation-1: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.

Detailed explanation-2: -Prokaryotes do not have cell nuclei: their structures are simple. Bacteria and archaea are all unicellular prokaryotes.

Detailed explanation-3: -Prokaryotes are simple organisms that lack membrane-bound organelles. All prokaryotes are unicellular. They consist of only one cell. Example: bacteria. They possess a ‘nucleoid’ instead of a true nucleus.

Detailed explanation-4: -Examples of unicellular organisms are bacteria, archaea, unicellular fungi, and unicellular protists.

Detailed explanation-5: -Prokaryotes are a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and archaea.
