All cells in the human body are diploid, except those used in sexual reproduction. Examples of diploid cells are blood, muscle and skin cells.
Diploid cells are organisms that consist of two copies of each chromosome, typically one inherited from the mother and another from the father. Diploid cells reproduce by a type of cell division called mitosis that takes place in the nucleus. It results in two daughter cells that have the same quantity and type of chromosomes as the parent nucleus.
Diploid cells comprise the majority of cells in the human body, and have twice the number of chromosomes as haploid cells, which are the gametes used in sexual reproduction. There is a total of 46 chromosomes in each human diploid cell, including skin, muscle and blood cells.Learn More
Although most of the cells in the human body renew themselves periodically, the majority of the neurons in the brain are produced before birth in a process called neurogenesis, and serve humans for their entire lives. Some portions of the brain, however, add new cells during infancy, and one part in particular, the hippocampus, adds cells throughout an individual's lifetime.Full Answer >
The longest cells in the human body are neurons. Neurons are cells within the nervous system and carry messages throughout the body.Full Answer >
Animal cells are eukaryotic cells, or cells that contain a membrane-bound nucleus. The nucleus holds the DNA of the cell that provides the cell with instructions for life.Full Answer >
Cells that need to perform high amounts of work, such as muscle cells in the heart and legs, fat cells and liver cells. Mitochondria are organelles which contain their own DNA. Animal cells generally have approximately 1,000 to 2,000 mitochondria.Full Answer >
