Which of the following is an inclusion body found in prokaryotes that is NOT bounded by any membrane?
Answer and explanation
Correct answer: A. Phosphate granule
- Step 1: Reserve materials in prokaryotic cells are stored in the cytoplasm in the form of non-membranous inclusion bodies.
- Step 2: These include phosphate granules, cyanophycean granules, and glycogen granules lying freely suspended in the cytoplasm.
- Step 3: In contrast, organelles in eukaryotes are bounded by lipid bilayers.
Answer
Phosphate granule.
Why not the others: Lysosome is a eukaryotic organelle enclosed by a lipid unit membrane; Gas vacuole in blue-green algae is formed of proteinaceous gas vesicles permeable to gases; Peroxisome is a eukaryotic membrane-bound organelle.
