Meiosis is the process by which reproductive cells divide twice to form four daughter cells. Each of these daughter cells are called haploid because they contain half as much genetic information (chromosomes) as the original cell. To remember this, try to think of HAPloid as HALFloid. The daughter cells that are created become gametes (eggs and sperm). This is why you have half your genetic information from your maternal line and half from your paternal line.
Mitosis takes place in somatic cells (any cells that are not reproductive). In mitosis, one cell divides into two identical daughter cells. These cells will replace worn out cells or facilitate growth. You can remember mitosis' connection to somatic cells by thinking of it as miTOEsis, as it would occur in the cells in your toe rather than your reproductive cells.
