Cytoplasm vs Protoplasm
All living things, whether plants or animals are composed of cells. These cells in turn are themselves a self contained unit meaning each cell is a living being. Cells are made up of a gel like substance called protoplasm which is the basic living material. Protoplasm is made up of hydrogen, oxygen, nitrogen, carbon, and sometimes sulfur and potassium. Only living beings have the capacity to make a new protoplasm or repair damaged one. Protoplasm is a gel like substance that is colorless and feels like a gel too. It contains a lot of water.
Protoplasm mainly consists of two parts, the nucleus, which is semi solid and located centrally. The other part is less viscous and softer. It is referred to as cytoplasm. All living things have different protoplasm. This means that protoplasm is not alike and there are millions of types of protoplasm. Despite such a great variance in their formation, they are made up of the same basic hydrogen, carbon, nitrogen and oxygen. Protoplasm is the storehouse of energy and all energy that plants and animals have is a result of this energy stored in protoplasm. Scientists have yet not been able to decipher the cause behind life in protoplasm.
Protoplasm = Cytoplasm + Organelles
All cells have a cell membrane which is the outer most living layer of all cells. This is very thin and allows entry of carbon dioxide, water, food material and other substances. It helps in keeping out harmful substances. Cell membrane is also made up of protoplasm.
Protoplasm is the living content of a cell that is surrounded by a plasma membrane (cell membrane). Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides.  In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. In prokaryotes the material inside the plasma membrane is the bacterial cytoplasm, while in gram-negative bacteria the region outside the plasma membrane but inside the outer membrane is the periplasm. The cytoplasm is a thick liquid residing between the cell membrane holding all the cell's internal sub-structures (called organelles), except for the nucleus. All the contents of the cells of prokaryote organisms (which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryote organisms the contents of the cell nucleus are separated from the cytoplasm, and are then called the nucleoplasm.
