During cell division, DNA is so that there is enough available to share between cells. Each is duplicated, and the cell parts responsible for cell functions are .
is the process of each of chromosomes being divided equally between two cells. A cell goes in order through before reaching cytokinesis, where both the and the cytoplasm are divided, resulting in two identical diploid cells.
This process increases the total number of cells in the body and enables growth. Growth can be tracked in babies using percentile charts, which give an indication of whether babies are growing at a healthy rate. At any point in their growth, per cent of babies will have masses below the 75th percentile curve on the chart.
A special type of cell, known as a stem cell, is capable of many times and into another type of cell. Human stem cells are mainly found in , while plant stem cells are present throughout life in structures known as . The cells in mature animals can only divide to perform or replacement.
