Difference from eukaryotic and prokaryotic

However, the mitochondria of today's eukaryotes have their own DNA blueprints that replicate independently from the DNA in the nucleus, and mitochondrial DNA has some similarity to prokaryotic DNA, which supports the endosymbiotic theory. This endosymbiotic relationship ultimately led to the smaller cell becoming a part of the larger cell, eventually losing its autonomy and much of its original DNA.' This smaller cell was maintained within the larger host cell, where it replicated and was passed on to subsequent generations. 'The smaller prokaryote could perform aerobic respiration, or process sugars into energy using oxygen, similar to the mitochondria we see in eukaryotes that are living today. 'Over time, a smaller prokaryotic cell was engulfed by this larger cell,' says Shanle. Well, according to endosymbiotic theory, it all started about 2 billion years ago, when some large prokaryote managed to create a nucleus by folding its cell membrane in on itself. You might be wondering how organisms got to be divided in this way.

'By separating the large DNA blueprints in the nucleus, certain parts of the blueprint can be utilized to create different cell types from the same set of instructions.' 'Many eukaryotic organisms are made up of multiple cell types, each containing the same set of DNA blueprints, but which perform different functions,' says Shanle. They're more of a two-bit operation in this sense. Prokaryotic cells have to do a lot of this same stuff, but they just don't have separate rooms to do it in. Other key organelles include the mitochondria, which processes sugars to generate energy, the lysosome, which processes waste and the endoplasmic reticulum, which helps organize proteins for distribution around the cell. This protects the DNA and allows the cell to fine-tune the production of proteins necessary to do its job and keep the cell alive. In contrast, eukaryotes have membrane-bound organelles that are used to separate all these processes, which means the kitchen is separate from the master bathroom - there are dozens of walled-off rooms, all of which serve a different function in the cell.ДЇor example, DNA is stored, replicated, and processed in the eukaryotic cell's nucleus, which is itself surrounded by a selectively permeable membrane. Prokaryotes don't have separate compartments for energy production, protein packaging, waste processing or other key functions.' 'They have a single 'room' to perform all the necessary functions of life, namely producing proteins from the instructions stored in DNA, which is the complete set of instructions for building a cell.

'Prokaryotes are much simpler with respect to structure,' says Shanle. In this way, all cells maintain internal homeostasis, or stability.

You can lock your doors and windows to keep out stray cats and burglars (the cellular equivalent to viruses or foreign materials), but you unlock the doors to bring in groceries and to take out the trash. One reason this analogy is helpful is because all cells, both prokaryotes and eukaryotes, are surrounded by a selectively permeable membrane which allows only certain molecules to get in and out - much like the windows and doors of our home. Prokaryotes have to get similar jobs done in a single room without the luxury of organelles.' 'The size and separation of functional 'rooms,' or organelles, in eukaryotes is similar to the many rooms and complex organization of a mansion. 'I think of a prokaryote as a one-room efficiency apartment and a eukaryote as a $6 million mansion,' says Erin Shanle, a professor in the Department of Biological and Environmental Sciences at Longwood University, in an email interview.
