Inclusion bodies are not covered by membranes and lie freely in the cytoplasm. They store reserve material such as phosphate granules. blue-green bacteria contain gas vacuoles which is an inclusion body.

Introduction:
Inclusion bodies are structures found in the cytoplasm of prokaryotic cells. They have various functions and are composed of different materials. In this question, we are asked to identify which statement regarding inclusion bodies in prokaryotes is not true.
Explanation:
The correct answer is option B, which states that inclusion bodies are bound by a single membrane. This statement is not true because inclusion bodies in prokaryotes are not bound by any membrane.
Functions of Inclusion Bodies:
Inclusion bodies serve as storage sites for various substances in prokaryotic cells. They can store reserve materials, such as glycogen, polyphosphates, and lipids, which can be utilized by the cell during times of nutrient scarcity. Inclusion bodies can also store enzymes, pigments, and other molecules that are required by the cell for specific functions.
Composition of Inclusion Bodies:
Inclusion bodies can be composed of different materials depending on their function. For example, gas vacuoles are inclusion bodies found in blue-green bacteria (cyanobacteria). They are composed of gas-filled vesicles that provide buoyancy to the cells, allowing them to move up and down in water bodies to access light and nutrients.
Location of Inclusion Bodies:
Inclusion bodies are generally found freely floating in the cytoplasm of prokaryotic cells. They are not bounded by any membrane and are distinct from other cellular structures like organelles. This allows them to be easily accessible for the cell to utilize their stored materials when needed.
Conclusion:
Inclusion bodies in prokaryotes serve as storage sites for various substances and do not have a single membrane surrounding them. The correct statement regarding inclusion bodies in prokaryotes is that they lie freely in the cytoplasm. Therefore, option B is not true.
