______ include/s glycogen, poly-β- hydroxybutyrate granules, sulphur granules and gas vesicles.

Cytoplasm

The correct answer is Option (4) -Cytoplasm

Cytoplasm includes glycogen, poly-β- hydroxybutyrate granules, sulphur granules and gas vesicles.

The cytoplasm is a jelly-like substance that fills the space inside a cell, excluding the nucleus. It's where many important cellular processes take place, and it contains various structures and molecules, including:

• Glycogen: A carbohydrate stored for energy
• Poly-β- hydroxybutyrate granules: Another type of energy storage molecule
• Sulphur granules: Stores sulfur, which is important for various cellular functions
• Gas vesicles: Gas-filled sacs found in some bacteria that help them regulate buoyancy

Flagella, plasma membrane, and mesosomes are all important cell structures, but they are not part of the cytoplasm itself.
