Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are

biology‚ cell theory is a scientific theory that describes the properties of cells‚ which are the basic unit of structure in all organisms and also the basic unit of reproduction. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory is one of the foundations of biology.The observations of Hooke‚ Leeuwenhoek‚ Schleiden‚ Schwann‚ Virchow‚ and others led to the development of the cell theory
