cytoplasm. The jellylike material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus. The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and (in green plants) chloroplasts, are contained in the cytoplasm. read more
The cytoplasm comprises three main parts. The main part, which makes up more than 50 percent of a cell's volume, is the cytosol. This gel-like substance is composed of water, dissolved enzymes and salts. The second major component of the cytoplasm is the cell's organelles. read more
The cytoplasm of the animal cell is a gel-like material made of water. It fills the cells and contains proteins and important molecules that are necessary for the cell. The cytoplasm is made of proteins, carbohydrates, salts, sugars, amino acids and nucleotides. read more
In cell biology, the cytoplasm is the material within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles – the cell's internal sub-structures. read more
