Also known as GO:0005737, cytoplasma

The cytoplasm is all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are the cytosol (a gel-like substance), the cell's internal sub-structures, and various cytoplasmic inclusions. The cytoplasm is about 80% water and is usually colorless.

AI overview

Cytoplasm is the gel-like material that fills cells, located between the cell membrane and the nucleus (in eukaryotic cells), and contains the cell's internal structures and various substances. It matters because it is where most of the cell's vital activities and processes take place, making it essential for the cell to function.

The cytoplasm is all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are the cytosol (a gel-like substance), the cell's internal sub-structures, and various cytoplasmic inclusions. The cytoplasm is about 80% water and is usually colorless.

The cytosol or cytoplasmic matrix or groundplasm, remains after the exclusion of the cell organelles and cytoplasmic inclusions. Microscopically it is a highly complex, polyphasic system in which all resolvable cytoplasmic elements are suspended, including the larger organelles such as the ribosomes, mitochondria, plant plastids, lipid droplets, and vacuoles.
