What are diploid cells?
Diploid cells are cells which contain 2 sets of chromosomes, which will later be divided into two sets of 23 chromosomes for each daughter cell. The total will come up to be 46 chromosomes. The other type of cell is a haploid. A haploid is a sex cell which contains 23 chromosomes. Later when the sperm enters the egg, or the egg meets the sperm the two sets of DNA (One from the sperm, and the other from the egg) will pair up to make another cell with 46 chromosomes. Different animals have different amounts of chromosomes. I have bases this answer on human cells.
