Cell cycle

Stage 1
-
Cells grow bigger and increase in mass while duplicating their DNA. They also increase there mitochondria, ribosomes and chloroplasts

Key points
In body cells, chromosomes are found in pairs
-
During the cell cycle the genetic material is doubled. It then divides into two identical nuclei in a process called mitosis
Before a cell can divide it needs to grow, replicate the DNA to form two copies of each chromosome and increase the number of sub cellular structures. In mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides. Finally the cytoplasm and cell membranes divide to form two identical cells
Mitonic cell division is important in the growth, repair and development of multicellular organisms

In asexual reproduction, the cells offspring are exactly the same as the parent
