The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.
If you look at the taxonomic classification there are 7 levels and they are 1. Kingdom; 2. Phylum; 3. Class; 4. Order; 5. Family; 6. Genus and 7. Species.
The taxonomic level phylum includes greatest number of species for a given genus.
