Every living cell that exists must contain at least one mitochondria, though some more active cells, such as those in muscles, contain more. This is because mitochondria are responsible for creating the energy that powers your movements
, even the most simple ones, such as breathing, or blinking. Fat cells also contain many more than one mitochondria, because they store large amounts of energy. A mitochondria will contain its own small chromosomes. These are usually only passed down through the mother.

First of all, prokaryotic cells do not contain a mitochondria, lets get that straight lol. Although the mitochondria is responsible for creating energy, it must go through a process called cellular respiration which includes sugars and oxygen (both of which are a products of photosynthesis which occurs in the chloroplast) to make ATP. I do believe that the mitochondria is important in the cell. However the chloroplast is obviously more important because it is what gives the mitochondria the essential components to fulfill its specialized functions, which is producing usable energy. Vote Chlorplast! :)
ReplyDeleteP.S. And I know that you will go on to answer me saying that the mitochondria is what gives the chloroplast energy, nevertheless we must not forget that according to the Endosymbiotic theory, millions of years ago, the chloroplast was a single cell organism. A debate that the chloroplast needs the mitochondria to survive is then just assuming and would not be valid.
How does the chloroplast give the mitochondria "essential components" if the chloroplast is only in half the number of cells that the mitochondria is? If that statement were to be true, than chloroplasts would have to be present in animalia as well, which they are not. I never said that the chloroplast needed the mitochondria to survuve, just that it helps it out enegy-wise.
DeleteBECAUSE ALL OF THE SUGARS ARE PRESENT IN EVERY CELL! Without chloroplast there would be no cellular respiration! The chloroplast does not need to be present in all cells if its byproduct is. Think of a food chain. Plants(primary source of sugars) are eaten by primary consumers, then the sugars are passed on to the secondary consumers and so on.
