Question

Granules, cyanophycean granules, and glycogen granules. Gas vacuoles are found in blue-green and purple and green photosynthetic bacteria.

Answer 1

Blue-green and purple and green photosynthetic bacteria are very important organisms because without them knowing the forms of life can exist these are the organism that can produce their own food using the materials from organic sources. Therefore they can also be called producers.

Complete answer:
The organisms that are capable of producing their own food known as autotrophs. Blue-green and purple and green photosynthetic bacteria come under this category. To make their own food they require certain raw materials that includes carbon dioxide, light energy, chlorophyll, and water. Those autotrophs that use energy from the sun are called photoautotrophs while those autotrophs that use chemical energy for the process of making food are called chemoautotrophs.
-Inorganic sources are used by autotrophs to make their food and they are also commonly referred to as primary producers because they occupy the base of the food chain.
The vacuoles in their cells are the hollow structures that are called the gas vacuoles and are lined by the membrane which is responsible for the deflation and inflation of the gas vacuoles resulting in these organisms floating and showing buoyancy. The cytoplasm of these organisms are generally filled with the cyanophycin which is found in the form of granules. Cyanobacteria along with purple and green photosynthetic bacteria are the bacteria-containing gas vacuoles. They help in the exchange of gases based on the environmental conditions. The cyanophycean granules present in them are responsible for the storage of nitrogen in them. All these granules, cyanophycean granules, and glycogen granules are known as the inclusion bodies present in these organisms.

Note:
Cell inclusions are non-living substances that are intracellular and are not bound by any membrane. These inclusive bodies are accumulated in the form of granular pigments, nutrients, and secretory products inside the cytoplasm. Examples of cell inclusions are lipids, glycogen, and pigments such as lipofuscin, melanin, and hemosiderin.
