Prokaryotic Cell

Prakaryotic cells attract me when it comes to the learning of cells. The figure that is shown on page 65 is amazing. There are so many things that are apart of this cell and without each one this cell will not survive. There is the ribisome which is where I can fin the protein synthesis taking place, then the inclusion body that is shaped like a little ball and this little things stores nutrients that are being taken in for later so that this cell can always have energy. Mesonomes in the shape of this pouch or puzzle looking piece when looked at from above stays on the inside of this cell which is the plasma membrane that will connect with cytoplasm and increase the surface area all around the cell wall. If I have looked correctly there are four things that stay inside the cell and operate the interior, which are the three above and this final one called the nucleoid. The nucleoid is in fact where the bacterial chromosome can be found which is almost like a bunch of strings all coiled up. I find the outside of the cell to be the most interesting just because of the things that it is capable of doing. The fimbriae is like hair all around the cell, this hair is what will grab on to things and stick to them and then there is the giant looking hair, which is the appendage sticking out which will allow this cell to transfer DNA to different bacterial cells. The most interesting thing to watch on this cell is the flagellum, the flagellum is this tiny sting like thing comeing out of the back of the cell and it spins just as a boat prop does. This is how the cell moves around, this makes it seem like some of the things that a cell does is why we have certaint things like the boat prop. So this is the structure of the prokaryotic cell and how it is made up. Without every aspect listed that I learned, the cell would not survive.
