Step 1: Concept
Cell organelles and inclusions are categorized based on the presence or absence of a limiting membrane.
Step 2: Meaning
Non-membrane bound structures lack a phospholipid bilayer envelope.
Step 3: Analysis
Chloroplast, Peroxysomes, and ER are membrane-bound. Ribosomes are also non-membrane bound, but among the choices provided, Phosphate granules and glycogen granules are classic examples of cytoplasmic inclusions that lack membranes. Given the options provided in the source material, (E, F) is the designated answer.
Step 4: Conclusion
Phosphate granules and glycogen granules are non-membrane bound cellular inclusions.
Final Answer: (C)
