Hi, I'm Jim Shields for About.com, and today I'm going to teach you about eukaryotic cells. A eukaryotic cell is a cell that has a nucleus, which is a part of the cell bound in a membrane called the nuclear envelope. The nucleus is important because it stores all the DNA of the cell. Things made up of eukaryotic cells are called eukaryotes, which include most complex life forms like mammals and plants.In this simplified drawing of an animal cell, you can see the nucleus, defined by the nuclear membrane. Eukaryotic cells stand in contrast to prokaryotic cells, which are mostly represented by single-celled organisms like bacteria. Unlike eukaryotic cells, which have a nucleus, prokaryotic cells have no nucleus. Their genetic material floats freely within the cell wall and they multiply through the process of binary fission –- as opposed to mitosis. Thanks for watching.
