In many bacteria, what does the cell membrane become invaginated and folded to from?
The bacterial genome contains
identify the correct statement(s):
(i) The surface area available for cellular functions in an eukaryotic cell is more than that in a prokaryotic cell.
(ii) The total genome size of a prokaryotic cell is always less than that of a eukaryotic cell.
(iii) Unlike eukaryotes, no special respiratory organelles are found in prokaryotes. Hence, they respire at a much lesser rate than eukaryotes.
(iv) Eukaryotic cells show various membrane-bound organelles such as chloroplasts and nucleus while ribosomes are the only membrane-bound organelles found in prokaryotes.
