how do haploid cells differ from diploid cells?
The diploid number of a cell is the total number of chromosomes it contains. In humans the diploid number is 46. This means that each cell contains 46 chromosomes. Haploid cells contain half the diploid number. In humans eggs and sperm are haploid which means they contain 23 chromosomes. when they fuse you get a diploid cell which grows into another being.
