Do you think you know everything about cells? You know they divide but they are divided in two groups. One group is Prokaryotes and the other is Eukaryotes. Both are group of cells but they have different meanings. Prokaryotes are cells that do not have a membrane-bound nucleus. In fact “prokaryotic” in Greek means “before nucleus”. Eukaryotes are cells that possess a cell membrane that holds genetic information. Eukaryotes also have an organized nucleus. Now that you know the meanings of prokaryotes and eukaryotes, keep reading to learn more of them.
Do you know you are made of prokaryote and eukaryote cells? Do you want to know how they work? Here, we are going to tell you how! Prokaryotes work without a nucleus, but they have DNA, prokaryotes divide or reproduce by a process called Binary Fusion. An interesting fact is that prokaryotes are the oldest bacteria in the world. Eukaryotes are younger Eukaryotes are younger cells so they have more characteristics, for example they have a nucleus and they reproduce by mitosis and meiosis.
Did you know there are two types of prokaryote cells? They are bacteria and archaea. The archaea is a bacteria that constitute a domain or a kingdom of single bacteria called microorganisms. Bacteria is a microorganism unicellular prokaryote that can cause sicknesses. Also there is the eukaryote cell, which divides into four, which are: animal, plant, fungi and protist. Some examples of fungi are mushrooms. An example of protist is amoeba.
The majority of cells are actually prokaryotic cells. The prokaryotes just have ten organelles, which are: nucleoid, ribosomes, plasmid, cytoplasm, cell wall, flagellum, plasma membrane, which is responsible for controlling what gets in and out of the cell, mostly it give access to the proteins. The last one is genetic material. Eukaryotes have around 20 organelles. Some of the most important organelles are: nucleus, endoplasmic reticulum, cytoplasm, ribosomes, mitochondria, Golgi apparatus, and vacuole.
Did you know there are organisms living and duplicating inside your body right now? Do you know how this happens? Well, we will start with the eukaryotes reproduction. First, the cell takes in nutrients, grows and duplicates its chromosomes. Then the nucleus divides and the divided nuclei are stablished in different cells. The reproduction process of the prokaryotes starts when the chromosomes in the middle of the cell divides and the chromosomes go to the opposite sides of the cell. The plasma membrane in the middle of both chromosomes closes and two new cells form.
