Prokaryote Cell – simplest and most ancient type of cells. There where the only form of life in Earth for billions of years before eventually giving rise to Eukaryote cells (2.7 billion years ago).
If you take a look at Prokaryote and Eukaryote side by side, you can see a number of differences. To begin with, prokaryote cells are a lot smaller than Eukaryote cells and have a simpler structure. But bare in mind that this simple structure is actually a good thing for Prokaryote because it allows them to reproduce very quickly and effectively. If you would look at the inside of Prokaryote cell, you would probably surprise at how simple it is; for example Prokaryote cells lack of Nucleus in fact the name Prokaryote actually gives you a hint about its structure. “Pro” means before and “kary” means nucleus.
The inside of Prokaryote cell is a single-celled organism and basically an open unit with no compartments. There is no membrane bound organelles. However, small structures called Ribosomes are scattered throughout Cytoplasm. The cell’s DNA is located in the region of Cytoplasm called the Nucleoid region. The Nucleoid region is not the same thing as Nucleus because it’s not enclosed by a membrane. Prokaryote …show more content…
The Eukaryote cells are either single-celled or multicellular organism. Eukaryote cells also gives a hint on its structure. “Eu” means true and “kary” means nucleus. In essence the word Eukaryote means “true nucleus”. Eukaryote cells evolved from Prokaryotes cells are much larger and more complex internally than Prokaryote cells. However, they share a few things in common. Both cells have DNA as genetic material, Ribosomes, Cytoplasm and both have Plasma membrane. Finally, the DNA of a Eukaryote is organized as multiple linear chromosomes as opposed to Prokaryote cells’ single circular
