Which of these statements is/are true ?
(i) The surface area avaiable for cellular function in a prokaryotic cell is less than that in a eukaryotic cell.
(ii) The total genome size of a prokayotic cell is always less than that of a eukaryotic cell.
(iii) Unlike eukaryotes, no special respiratory 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 nucles while ribosomes are the only membrane bound organelles found is prokaryotes.

Options

A. (i) and (ii)
B. (iv) only
C. (iii) only
D. (i), (ii) and (iv)

Answer

A

Explanation

Unlike eukaryotes, prokaryotes do not have membrance bound organelle for respiration but many enzymes needed for cellular respiration are attached to the plasma membrane, which may fold and extend into cell. Ribosomes are the only cytoplasmic organelles in prokaryotes and they are not membrane bound.
