cytoplasm
n.
(Biology) protoplasm of the cell (located outside the nucleus and membrane)
Cytoplasm
Cytoplasm is a gelatinous, semi-transparent fluid that fills most
cells.
Eukaryotic cells contain a
nucleus that is kept separate from the cytoplasm by a double membrane layer. The cytoplasm has three major elements; the
cytosol,
organelles and
inclusions. The
cytosol is the gooey, semi-transparent fluid in which the other cytoplasmic elements are suspended.
Cytosol makes up about 70% of the cell and is composed of water, salts, organic molecules, and enzymes that are necessary for the cell to catalyze reactions. The
organelles are the metabolic machinery of the cell and are like little organs themselves. The major
organelles that are suspended in the
cytosol consists of the
mitochondria,
proteins,
ribosomes, the
endoplasmic reticulum, the
Golgi apparatus,
lysosomes, and the
cytoskeleton. The
inclusions are chemical substances that store nutrients, secretory products and pigment granules.
