The control center of a cell is the nucleus, also known as kernel of the cell. In the following sections, we shall explore the structure and functioning of a nucleus, and try to understand the working of this smallest processing unit in nature.  The nucleus has several major functions. First, it is the storage location for DNA, the genetic material of the cell. Second, it is the control center where various proteins a … nd enzymes are either upregulated or downregulated, which then controls what processes the cell will perform. Third, it is the location where new ribosomes are assembled. It holds the vital DNA of the cell. It contains hereditary materials known as chromosomes, acts as a control center for cell activities, and controls cell division. The function of nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The Cell Nucleus: The cell nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell. The cell nucleus is bound by a double membrane called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. Like the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer. In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel) is a membrane-enclosed organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types have no nuclei, and a few others have many. nucleus is the brain that controls the cell and holds the DNA.        Cell membrane   Controls what substances can get into and out of the cell.   Cytoplasm …   Jelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm. First, it is the storage location for DNA, the genetic material of the cell.

Definition: The nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is commonly the most prominent organelle in the cell. The nucleus is surrounded by a structure called the nuclear envelope.  Animal cell nucleus is a membrane bound organelle. It is surrounded by double membrane. The nucleus communicates with the surrounding cell cytoplasm through the nuclear pores. The DNA in the nucleus is responsible for the hereditary characteristics and protein synthesis. Nucleus the most prominent organelle of the cell. The number of nuclei may vary, they may be uni-nucleate (single nucleus), bi-nucleate (two nuclei) or even multi-nucleate. Nucleus is present in all eukaryotic cells, they may be absent in few cells like the mammalian RBCs. The genes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression —the nucleus is, therefore, the control center of the cell. nuclei; from Latin nucleus or nuculeus, meaning kernel) is a membrane-enclosed organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types have no nuclei, and a few others have many. Nucleus is the control center of the cell. The genes inside the nucleus tell the cell what to do, and thus, tells the body what to do. There are also nucleolus inside th … e nucleus. Nucleolus makes parts of ribosomes that are sent out to the cytoplasm. It holds the vital DNA of the cell. It contains hereditary materials known as chromosomes, acts as a control center for cell activities, and controls cell division. The function of nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is a spherical-shaped organelle present in every eukaryotic cell. It is the control center of eukaryotic cells, responsible for the coordination of genes and gene expression. The structure of a nucleus encompasses nuclear membrane, nucleoplasm, chromosomes and nucleolus. Nucleus is separated from the rest of the cell or the cytoplasm by a nuclear membrane. Structure of Cell Nucleus. The cell nucleus consists of a nuclear membrane (nuclear envelope), nucleoplasm, nucleolus and chromosomes. Nucleoplasm, also known as karyoplasm, is the matrix present inside the nucleus.
