According to the College of DuPage, any of the various cells that make up plants, animals, fungi and protists are eukaryotic. This includes the skin cells of humans or the xylem cells of trees. Eukaryotic cells are more evolutionarily advanced than prokaryotic cells, as eukaryotes typically contain a membrane-bound nucleus, which prokaryotes lack. Additionally, eukaryotic cells possess many distinct organelles, which prokaryotic cells lack.Know More
According to Georgia State University, the basal split in the evolutionary tree of life occurred when eukaryotic cells arose. Bacteria and archaebacteria are prokaryotic organisms, while all living organisms that are more advanced than this are eukaryotic. Some of the advances seen in the evolution of eukaryotic organisms include linear, rather than circular, DNA and the development of numerous organelles within the cytoplasm of the cell. The linear DNA of eukaryotic cells is found primarily in the nucleus. Eukaryotic cells feature a number of internal organelles, each of which carries out a distinct function. For example, the mitochondria produce energy for the cell.
According to About.com, mitochondria have many characteristics that make them similar to prokaryotic cells. Mitochondria have their own DNA, which is arranged in circular fashion, similarly to most prokaryotes. In addition to providing power for the cell, mitochondria play a role in cell division, growth and death.Learn more about Cells
Eukaryotic cells all feature a nucleus, and their organelles are enclosed inside membranes. They also have a plasma membrane, which is a layer of phospholipids that surrounds the whole cell, and they feature an internal cytoskeleton.Full Answer >
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 >
Prokaryotic and eukaryotic cells differ in many ways, notably in the structure of their cell walls, the arrangement of their genetic material and their internal arrangement of cellular machinery. Eukaryotes, a group that encompasses all large organisms, also tend to reproduce sexually, while prokaryotes show more variation in reproductive methods.Full Answer >
Orange County Community College explains that cyclins are one of many proteins within a eukaryotic cell that regulate the cellular life cycle. All cyclins belong to the same genetic family, which contains several different subtypes.Full Answer >
