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 and are not membranous. Most are membranous.
Eukaryotic cells, whether from animals, plants, protists, or fungi, are the most structurally advanced of the major cell types. Eukaryote are single-celled or multicellular organism whose cells contain nucleus and any other structures (organelles) enclosed within the membrane that perform specific functions. The surface of the cell is covered with a thin film or plasma membrane, which is the boundary that separates the living cell from its nonliving surroundings. Plasma membranes are composed mostly of proteins and lipids (Simon, 02/2012, p. 59-60).
The most important and largest cellular organelle is the nucleus, which houses most of the eukaryotic cell’s DNA and is surrounded by a double membrane. The nucleus contains most of the cells genetic material. The nucleus is the control center of the cell.
“The plasma membrane is the edge of life, the boundary that separates the living cell from its nonliving surroundings. The plasma membrane is a remarkable film, so thin that you would have to stack 8,000 of these membranes to equal the thickness of the page you are reading. Yet the plasma membrane can regulate the traffic of chemicals into and out of the cell. The key to how a membrane works is its structure” (Simon, 02/2012, p. 60).
Other than the previously mentioned nucleus, below are other organelles commonly found in eukaryotic cells. Comparison of structures between animal and plant cells (Table 1.0).

If a cell was a restaurant the cell wall would be like the walls of the restaurant because the walls protect the restaurant from the outside and gives shape to the restaurant in the same way the cell wall protects,supports,and gives shape to the cell. The cell membrane would be like the doors of the restaurant because the doors allow people to go
As for organisms in the world from humans to the smallest microbe, they directly reflect upon biodiversity, in respect to the appearance, size and expression. The reason behind this is caused by the genetic material found in each and every cell that composes each organism. Given that there are two types of cell organizations found in life, comparison of both ‘eukaryote’ and ‘prokaryote’ genomes will provide a better understanding for such diversity. ‘karyote’ refers to the nucleus, and also ‘pro’ means ‘absence’ and ‘eu’ means ‘presence’. Therefore the words prokaryote and eukaryote reflect upon the individual cell organization. In contrast, the both organizations show discrepancies as well as similarities which ultimately make them unique to one and other.
These organelles produce chemical reactions from the energy that the sun gives them. The Golgi complex's structure is made up of many flattened membranes sacs that are surrounded by tubules or vesicles. These are called the cisternae. The golgi complex accepts vesicles from the endoplasmic reticulum and modifies them for usage in the cell.

Eukaryotic cells share several distinguishing features, such as: cytoplasm within specialized organelles such as the mitochondria, chloroplast, the Golgi complex, both a rough and smooth endoplasmic reticulum, a nuclear envelope that isolates DNA from the cytoplasm, and a endomembrane system that provides structure and function to the organelles of the cell. Both the mitochondrion and chloroplast are energy transducing organelles, meaning that they transform energy from one form to another, and are believed to be evolved from free living prokaryotes as held by the theory of endosymbiosis. This theory suggests that infolding of the plasma membrane coupled with the absorption of a prokaryotic cells by other prokaryotes could evolve into a later, more complex and specialized type of cell and is proofed by related morphological features such as between cytobacteria and chloroplasts, and between mitochondria and aerobic prokaryotes. Further substantiation includes mitochondria and chloroplasts reproduction through binary fission like prokaryotes, the presence of DNA in both free living prokaryotes and in energy transducing organelles (apart from in the nucleus), protein synthesis and the presence of enzymes and ribosomes where the ribosomes of prokaryotes are comparable to those in mitochondria and chloroplast,
Prokaryotic cell: have no membrane covered organelles, they also have circular DNA and bacteria, Eukaryotic cell: have membrane covered organelles, they also have linear DNA and all other cells. Also the cell cycle is short in prokaryotic cells, roughly taking about 20-26 minutes to complete. And in eukaryotic cells, the cell cycle is long, it usually takes about 12-24 hours to complete. Below is a table of some of the differences between the cells:
A)Is incorrect because all cells require ribosomes (Module 14, slide 4) . Ribosomes are important since they make proteins which are part of the basic building blocks of life (Campbell 102).

A. The formation of eukaryotic cells and its nucleus and organelles occurred due to more complex life. The infolding of the cell membrane created the nucleus and endomembrane system. The organelles formed were the golgi bodies, vesicles, plasma membrane and the endoplasmic reticulum.

The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
