First and foremost, somatic cell division only divides once. On the other hand, the reproductive cell division's number of divisions is 2. Also, reproductive cell division has prophase 1 and 2, metaphase 1 and 2, anaphase 1 and 2, and telophase 1 and 2. Reproductive cell division also has 4 resultant cells as opposed to the 2 resultant cells of somatic cell division. Reproductive cell division also has only one set of 23 chromosomes and somatic cell division has two sets of 23. Both processes are of great significance. Somatic cell division is important for growth and for repair. Reproductive cell division, on the other hand, is important because it allows the sexual reproduction of organisms.
The interphase is significant because this is the phase that gives time for the cell to grow and replicate DNA.
