Osteocytes, also known as bone cells, have all the organelles found in other eukaryotic cells, such as a nucleus, mitochondria, cell membrane and endoplasmic reticulum. The major difference is that bone cells do not divide or undergo mitosis.Continue Reading
Osteocytes are eukaryotic cells with the characteristics and organelles of other eukaryotic cells. Among these is the nucleus that contains genetic material. Although they have genetic material, osteocytes do not undergo mitosis because, according to How Stuff Works, osteocytes are old, retired osteoblasts. They continue to function but at a reduced level. Osteocytes have a life of 25 years before they are replaced by other osteocytes.
The mitochondria in osteocytes is another organelle. This one produces the energy that propels the cell. The endoplasmic reticulum organelle is involved in protein synthesis. The cell membrane surrounds the cell's cytoplasm.
According to the University of Pennsylvania, osteocytes are critical to the bone matrix, which is made up of collagen and proteoglycans. Osteoblasts, the younger versions of osteocytes, form a layer upon which the matrix forms. Once this occurs, osteoblasts become part of the matrix and become osteocytes. The bone matrix survives only as long as the osteocytes survive. Once the osteocytes die, the matrix follows, and the process begins again.Learn more about Cells
There are more than four organelles that are common to most eukaryotic cells, with organelles such as the nucleus, mitochondria, Golgi apparatus and ribosomes. Other organelles common to eukaryotic cells include the lysosomes, endoplasmic reticulum, vacuoles, chloroplasts and cell walls.Full Answer >
An animal cell contains a nucleus, cytoplasm that contains the various organelles and a cell membrane, also called a plasma membrane. The nucleus is the largest of the organelles and governs cell activity. It also contains chromosomes, made up of tiny strands of DNA that replicate when the cell divides.Full Answer >
There are three bodies responsible for transport in the cell including the endoplasmic reticulum, the vesicles and the cell membrane. The endoplasmic reticulum moves materials within the cell body, while the vesicles move proteins to the cell membrane, and the membrane transports materials in and out of the cell.Full Answer >
The smooth endoplasmic reticulum, or smooth ER, performs functions in several metabolic processes, including synthesis of steroids, lipids and phospholipids, as well as the metabolism of carbohydrates, elimination of drugs from the system and attachment of receptors to cell membrane proteins. Both the smooth and rough endoplasmic reticulum form an organelle in eukaryotic organisms creating a network of tubes or sacs called cisternae, but it is the smooth endoplasmic reticulum that helps the body eliminate a number of toxins.Full Answer >
