humen skin cells only live for a few days then they get replaced
A virus is a relatively long molecule, not a cell.
In a prokaryotic cell, there is no nuclear membrane surrounding the chromotin, while in a eukaryotic there is one. in both, the DNA is attached to proteins which create long fibers of chromotin.
this are organelles enclosed by a membrane
Cells have all different shapes and sizes depending on what type of cell it is. For instance, a nerve cell is typically long and about 100 centimeter.

The duration of mitosis of normal epidermis is approximately 90 min.
In a eukaryotic cell DNA is stored in a nucleus as chromatin ( unless the cell is in the process of mitosis in which the DNA would arrange itself as chromosomes) However a prokaryotic cell has no nucleus, the genetic material is stored in the cytoplasm of the cell, prokaryotic cells also have a plasmid which is a ring of DNA which is separate to the main genetic material. This plasmid contains DNA not found in the main genetic material. The plasmid is also in the cytoplasm.

Eukaryotic cells all have a nucleus. Eukaryotes are organisms that are multicellular, although there are some examples of single cellular eukaryotes. So eukaryotic cells can be either cells with a nucleus or a eukaryotic organism's cell. hope that helps. Comments from others: Katia Vazquez: "It really helped! I needed that answer alot!!!!"
a network of long protein strands that helps to support the cell

No. Almost all plant and animal cells are Eukaryotic, and there are a wide variety of shapes, from the long and slender sperm to a rigid cuboid epithelial cell.

Is axon

Certain prokaryotic and eukaryotic cells in the human body have flagellum. An example of a eukaryotic flagellated cell is the sperm cell, which uses its flagellum to propel itself through the female reproductive tract.
