Bacteria are refered to as prokaryotes because :
(a) They have no chlorophyll
(b) They are unicellular
(c) They are free living
(d) They do not have a true nucleus.
(d) They do not have a true nucleus.
Prokaryotic cells have cell organelles but they lack membrane-bound cell organelles like chloroplast, mitochondria etc. and even a well-defined nucleus is absent which states that they have a simpler cell organization and bacteria are unicellular organisms with very simple cell structure lacking a proper nucleus and membrane-bound organelles, so they are called prokaryotic.
