LIFE SCIENCE

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.

Detailed explanation-2: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-3: -Answer and Explanation: A single-celled microscopic prokaryotic organism can either be called a bacteria or archaea. The difference between bacteria and archaea is that archaea are more closely associated with eukaryotes than bacteria.

Detailed explanation-4: -Prokaryotes lack all membrane-bound organelles, including nuclei, mitochondria, endoplasmic reticulum, chloroplasts, and lysosomes. Both prokaryotes and eukaryotes contain ribosomes. Ribosomes are not membrane-bound, and are primarily composed of rRNA. Prokaryotes require ribosomes in order to synthesize proteins.
