Hello! It is I, the Centriole! There are many obvious and non-obvious reasons why I should be chosen as top cell, but before I tell you these reasons, let me inform you about myself. To begin I am located beside the nucleus and rough endoplasmic reticulum in the cell. A second fact you should know is that I am composed of nine sets of triplet microtubules. The reason why I have so many microtubules is because due to my amazing organization skills, it is my job to organize all of these microtubules during their assembly. I organize microtubules in mainly animal cells. Most plant cells lack centrioles all together because my organization is not essential in all eukaryotes. Now that you know a little more about me, I shall explain my essential role in the interphase stage of mitosis. As you know during the S and G2 phase DNA is replicated then continues to grow. My role during these two phases is to replicate to form two new centrosomes. These new centrosomes then go on opposite sides of the dividing nucleus and are both used as poles for the mitotic spindle. As you can see my role is essential during the interphase stage of mitosis and without me animal life would seize to exist. In conclusion, I should be nominated as top organelle for my perfect organization skills and role in animal life.

Hold on a minute, Centriole! You're throwing around some big ideas for such a small organelle! How could you possibly think that you are the most important organelle of us all? I mean, you're ONLY found in an animal cell! You even said yourself, your skills are not required in all eukaryotes! Where as I, the mighty ribosome, am vital for life in ALL cells - animal, plant, eukaryotic, prokaryotic, YOU NAME IT! I produce all the proteins in the cell. These proteins are necessary for a vast variety of cell functions including, but not limited to, fighting viruses, growth, metabolizing and reproduction. That's right - mitosis would be IMPOSSIBLE without my proteins! You think you play an important role in cell division, but in reality, it is ME, the fundamental reason cells are even able to divide, that's the true star here!
ReplyDeleteSee you in the cell!

Centriole, centriole, centriole...you claim that you are the most important organelle in the cell, but I`m afraid that you are sadly mistaken. I mean, you yourself said that you mainly function in animal cells because your functions aren`t essential in most eukaryotic cells! If you truly were the most important organelle in the cell, then you would be present in all plant cells at the very least! Unlike the centriole, I, the vacuole, am present in all plant and fungal cells along with some protist, animal, and bacterial cells too.
ReplyDeleteBesides this though, it is also said that centrioles are involved in the formation of mitotic spindle fibres which aid in the separation of chromosomes during mitosis. Although this is true, it has been proven that spindle fibres in animal cells can self-organize themselves which means the role of centrioles are not obligatory. This is especially true in plant cells because the microtubules form spindle fibres and can function without the help of centrioles at all!
This being said, I cannot argue the centrioles importance in cilia assembly. My main point that I want to stress though, is that the centriole has two primary roles: the formation of cilia and centrosomes and one of these jobs isn`t even that important. Sure animal cells benefit from the presence and functioning of centrioles, but its role isn`t mandatory. So with all this said, do you really think that the centriole is a valid candidate for the honour of becoming the most important organelle in the cell? Think about this when you have to decide who to vote for, and remember that the vacuole performs a number of functions that are useful and essential not only to the health of the cell, but also to the health of you.
