Eukaryotic cells are the most structurally advanced of the major cell types. Describe the structure and function of each of the eukaryotic organelles. Distinguish between those that are membranous and those that are non-membranous. Most are membranous. Eukaryotic cells, whether animal, plant, protist or fungal, are the most structurally advanced of the major cell types. Eukaryotes are unicellular or multicellular organisms whose cells contain the nucleus and any other structures (organelles) enclosed within the membrane that perform specific functions. The surface of the cell is covered by a thin film or plasma membrane, which forms the boundary that separates the living cell from the non-living environment. Plasma membranes are mainly composed of proteins and lipids (Simon, 02/2012, p. 59-60). The most important and largest cell organelle is the nucleus, which houses most of the DNA of the eukaryotic cell and is surrounded by a double membrane. The nucleus contains most of the genetic material of the cells. The nucleus is the control center of the cell. “The plasma membrane is the boundary of life, the boundary that separates the living cell from its nonliving environment. The plasma membrane is an extraordinary film, so thin that you would have to stack 8,000 of them to equal the thickness of the page you are reading. Yet the plasma membrane can regulate the trafficking of chemicals into and out of the cell. The key to the functioning of a membrane is its structure” (Simon, 02/2012, p. 60). In addition to the previously mentioned nucleus, the following are other organelles commonly found in eukaryotic cells.
