How Are Prokaryotic And Eukaryotic Cells Alike

As people look around at others they may think everyone is completely different. This is true-- every person has different characteristics, but the one thing that we have in common would be cells. In fact every living thing is composed of cells: plants, animals, bacteria etc. Cells exist in different shapes and sizes. They also differ depending on the function they have in an organism. To make things simpler, cells are categorized into two vast groups: Prokaryotic and Eukaryotic Cells. These two types of cells are different from each other while still sharing some similarities. Eukaryotic and Prokaryotic Cells perform the same functions in the same way, both also carry DNA, but internally they are organized differently. Prokaryotic and Eukaryotic Cells are different from each other because they have different internal structure. To begin with Eukaryotic Cells are much more complex than Prokaryotic Cells. A Eukaryotic Cell will always be larger than a Prokaryotic Cell. For example, Prokaryotic Cells do not carry a nucleus while a Eukaryotic Cells do. Another internal difference would be that Prokaryotic Cells are always unicellular and Eukaryotic Cells are often multicellular. Being unicellular means an organism lacks in tissues and specific organs. If an organism is multicellular it will have a well
This makes sense because Eukaryotic cells consist of a nucleus and a nuclear membrane. Since Eukaryotic cells are large a nucleus is necessary. The purpose of the nucleus is to set apart the DNA related functions of the Eukaryotic cell into a smaller space. Prokaryotic Cells do not have a nucleus because it is not necessary. Since Prokaryotic Cells are smaller all the DNA material inside the cell is already close together. The DNA of a Prokaryotic Cell is circular, which means it has no ends. On the other hand, Eukaryotic DNA is linear, which means it has two
