   What is a cell nucleus?

   • The cell nucleus can be seen on the left side of the cell. It is the large purple circle. Remember that this is a cross-section view, and in reality the nucleus would be more of a sphere. In animal cells it usually takes a spherical shape if there is enough room within the cell.

   What is the function of nucleus in a cell?

   • The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

   Where is the nucleus located in a cell?

   • The nucleus is a double membrane-bound organelle located centrally only in a eukaryotic cell, enclosing the DNA, the genetic material. It is the most important and defining feature of all higher organisms, including plant and animal cells, whose main function is to control and coordinate the functioning of the entire cell.

   What is a nucleus surrounded by?

   • The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments called the nuclear matrix, and is enveloped in a double membrane called the nuclear envelope. The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.

   How big is a nucleus in a cell?

   • The word ‘nucleus’ (plural: nuclei) is derived from the Latin word ‘ nucleus ‘, meaning ‘kernel’ or ‘ seed ’. The largest and most prominent organelle in the cell, the nucleus, accounts for almost 10% of the volume of the entire cell. In mammalian cells, the average diameter of the nucleus is approximately 6 µm in size.

   The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.
