In our previous article we learned about Prokaryotes and Eukaryotes. We also said that Prokaryotes do not have true nucleus while Eukaryotes have true nucleus. However, that’s not the only different. Prokaryotes do not have organelles while Eukaryotes have organelles.
2. Wondering what organelles are? Well, just like our body has organs such as heart, lungs, kidneys, liver etc. that perform some special functions, the cells also have some organs (at cellular level of course). These cellular organs are also designed to perform specific functions. These cellular organs are called organelles.
3. The most important feature of organelles is that they are bound by membranes . If something is inside the cell and is not bound by membranes, it cannot be classified as organelle.
4. Talking of Cell Membrane, both Prokaryotic and Eukaryotic cells have Cell Membrane or Plasma Membrane. In fact, they are same in both types of cells with a few exceptions of course.
5. The job of the Plasma Membrane is to ensure that the cell components (that is, the things that are present inside the cell) are held together. Also, the Plasma Membrane or the Cell Membrane is responsible for substance passage in and out of the cell.
6. Inside the Cell Membrane or the Plasma Membrane, you can find what is known as Cytoplasm. This Cytoplasm is present in both Eukaryotes and Prokaryotes.
7. The organelles that are present in Eukaryotes are embedded in the Cytoplasm. Since Prokaryotes don’t have any organelles, you won’t find any organelle embedded in the Cytoplasm of the Prokaryotes.
8. Inside both Eukaryotes and Prokaryotes, you will find something called Ribosomes. These Ribosomes are not organelles because they do not satisfy the necessary condition – that is, they are not bound by membranes.
9. These Ribosomes are actually sites of protein production inside the cells. Proteins are actually extremely important because they are needed not only for the functioning of the cells but also for the structure of the cells
10. When you put a cell under a microscope, you will see various things. In case you put a plant cell under a microscope, you will see what is known as Cell Wall. This Cell Wall is absent in case of animals (including humans).

i gave u my notes owo they are right ^^
