• A. inclusion bodies
• B. chromatophores
• C. pigments
• D. mesosomes

Answer 1

The correct option is (A):

Explanation of the correct option:

1. Phosphate granules, cyanophycean granules, and glycogen granules are examples of inclusion bodies.
   
2. Reserve material is stored in the form of inclusion bodies in prokaryotic cells.
   
3. These are non-membrane bound structures and lie freely in the cytoplasm.​

Explanation of the incorrect options:

Option (B):

1. Chromatophores are membranous extensions (structures formed by extension of plasma membrane) in cyanobacterial cells that contain pigments.​

Option (C):

1. The pigments are chromogenic or colored substances that are present inside the cells providing color to specific cells.
   
2. Example: chlorophyll in plant is a green pigment. ​

Option (D):

1. Mesosomes are formed due to infoldings of the plasma membrane.
   
2. These structures contain enzymes that help in cellular respiration.
   
3. These are found in bacterial cells.

Final Answer: Phosphate granules, cyanophycean granules, and glycogen granules are examples of inclusion bodies.
