Unlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others; and 3) several, rod-shaped chromosomes. Because a eukaryotic cell’s nucleus is surrounded by a membrane, it is often said to have a ...

Prokaryotic cells are smaller (as a general rule) and lack much of the internal compartmentalization and complexity of eukaryotic cells. No matter which type of cell we are considering, all cells have certain features in common, such as a cell membrane, DNA and RNA, cytoplasm, and ribosomes.
The significant difference between eukaryotic and prokaryotic is that eukaryotic organisms do not possess a true nucleus and membrane-bound organelles, whereas the prokaryotic organisms display a complex cell organization.
Eukaryotic cells contain membrane-bounded compartments. They contain ribosomes that are smaller than those of prokaryotic cells. They contain many organelles in the cytoplasm.

The primary difference between prokaryotes and eukaryotes involves the role of membranes throughout the cell. Eukaryotes feature a true nucleus, with a lipid bilayer separating the genetic material from the rest of the cell (this membrane is known as the nuclear envelope).

Fermentation is performed by both prokaryotic and eukaryotic cells, but the best example is yeast which produces ethanol from glucose in the absence of oxygen. All cells can be classified into one of two groups based on the presence or absence of a nucleus and membrane-bound organelles.

and eukaryotic cells is the presence of membrane-bound organelles, a feature that only eukaryotes have. Organelles of the endomembrane system separate functions within the eukaryotic cell, like a bunch of tiny factories that work together to help the cell run.

Prokaryotic cells are rather simple cells which only consist of a few organelles and lack a true nucleus. In comparison to eukaryotic cells, prokaryotic cells do not have a nucleus which contains their genetic material. Rather, prokaryotic cells contain a nucleoid which is a DNA/protein complex.
The defining feature that sets eukaryotic cells apart from prokaryotic cells (Bacteria and Archaea) is that they have membrane-bound organelles, especially the nucleus, which contains the genetic material, and is enclosed by the nuclear envelope. The presence of a nucleus gives eukaryotes their...
There are substantial differences between group I chaperonins, found in prokaryotic cells, and the distantly-related group II chaperonins found in Archaea and Eukarya. Group I chaperonins, such as GroEL of E. coli , require a ring-shaped cofactor, GroES, that upon binding acts as a lid for the cavity, creating a folding chamber that encloses ...

The main difference between normal and cancer is one of the growth and differentiation: most cancer cells are in their structure more like those of the young organism (fetus) than those of the adult.
The presence of whip-like flagella or short, hair-like arrays of many cilia protruding from cell surfaces is a striking visual feature of many protists and animal cells (figure 1). Historically, distinguishing between a flagellum and a cilium was often made on the basis of organelle length (flagella are typically longer than cilia) or organelle ...

Explain the difference between a proto-oncogene and a tumor suppressor gene. A proto-oncogene is a segment of DNA that codes for one of the positive cell cycle regulators. If that gene becomes mutated so that it produces a hyperactivated protein product, it is considered an oncogene. Eukaryotic cells have a membrane-bound nucleus. Animal cells and plant cells are eukaryotic. Eukaryotic cells have many organelles that perform functions within the cell. Some organelles are big enough to be seen with a light microscope. An electron microscope is needed to see all organelles in detail.
