Detailed explanation-1: -Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules.

Detailed explanation-2: -The portion of the cytoplasm surrounding organelles is called cytosol, which is the liquid part of the cytoplasm.

Detailed explanation-3: -The cytoskeleton is a group of fibrous proteins that provide structural support for cells, but this is only one of the functions of the cytoskeleton. Cytoskeletal components are also critical for cell motility, cell reproduction, and transportation of substances within the cell.

Detailed explanation-4: -Just as the fluid inside a cell is called cytoplasm, the fluid in the nucleus is called ‘nucleoplasm’. It is enveloped by the nuclear membrane and consists of chromatin (chromosomes) and nucleolus.

Detailed explanation-5: -Sarcoplasm is the cytoplasm of a muscle fibre. It is a water solution containing ATP and phosphagens, as well as the enzymes and intermediate and product molecules involved in many metabolic reactions.
