UPSC NDA-1 – 2018
A) Cell wall: Many prokaryotes have a cell wall (though different in composition from eukaryotic cell walls like those in plants or fungi).
B) Mitochondria: Mitochondria are membrane-bound organelles responsible for cellular respiration and ATP production in eukaryotic cells. They are *not* found in prokaryotic cells. In prokaryotes, respiration occurs in the cytoplasm and across the cell membrane.
C) Plasma membrane: The plasma membrane (cell membrane) surrounds the cytoplasm and is present in *all* cells, both prokaryotic and eukaryotic.
D) Ribosome: Ribosomes are responsible for protein synthesis and are found in the cytoplasm of *all* cells, both prokaryotic and eukaryotic (though prokaryotic ribosomes are 70S, and eukaryotic ribosomes are 80S).
