Prokaryotic Cells: Prokaryotes, such as bacteria, lack membrane-bound organelles and store reserve materials in the cytoplasm.
Reserve Materials: These include glycogen, polyphosphate, and polyhydroxybutyrate, which are stored as granules or inclusion bodies. Inclusion bodies are specialized structures that accumulate these reserve materials.
Option Analysis:
(1) Exclusion and inclusion bodies: "Exclusion bodies" is not a recognized term; only inclusion bodies are relevant. Incorrect.
(2) Fat bodies: This term applies to eukaryotic organisms (e.g., insects) for fat storage, not prokaryotes. Incorrect.
(3) Exclusion bodies: Not a valid term for reserve material storage in prokaryotes. Incorrect.
(4) Inclusion bodies: Correctly identifies the structures where reserve materials are stored in prokaryotic cytoplasm. Correct.
Conclusion: The correct answer is (4) Inclusion bodies, as they are the primary storage form for reserve materials in prokaryotes.
