Cells can be divided into 2 major groups:. Somatic (body): most of body tissue and organs. Germ: found in reproductive organs, develop into gametes. Gametes are sex cells – ova (eggs) & spermatozoa (sperm). Organisms that reproduce sexually are generally diploid: each cell contains two sets of chromosomes—a maternal chromosome set and a paternal chromosome set—one inherited from each parent. . .

Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the 1 identify the stages of meiosis. Only diploid cells caages of meiosis in a diploid cell where 2N = 6Meiosis involves 2 consecutive cell divisions. Since the DNA is duplicated result is 4 haploid cel
