Prokaryotes are characterised by
Answers
Answer:
All prokaryotes have chromosomal DNA localized in a nucleoid, ribosomes, a cell membrane, and a cell wall. The other structures shown are present in some, but not all, bacteria.
ANSWER
Prokaryotes lack membrane bound organelles like nucleus, mitochondria and chloroplast. Prokaryotic cells are unicellular organisms, which reproduce through binary fission. In some cases, few prokaryotic organisms also reproduce by budding. Prokaryotic cells have a cell envelope, which generally consists of a capsule, cell wall (chitin and mucopolysaccharides), cytoplasm, plasma membrane, cytoplasm region or nucleoid region, ribosome, plasmids, pili and flagella. They are autotrophs, phototrophs, chemotrophs and heterotrophs.
Prokaryotes are unicellular organisms that lack membrane-bound organelles. They also lack true nucleus. They have nucleoid, genetic material without nuclear envelope. They posses ribosomes in the cytoplasm. They are also characterized by absence of internal compartmentalization. All prokaryotes have 70S ribosomes. The 70S ribosome is made up of a 50S and 30S subunits. Examples of prokaryotes include bacteria, cyanobacteria.
