Centriole for best Organelle. Without me, there would be no you.


Why vote for us, the centrioles?

       We are barrel shaped structures. Present only in eukaryotic animal cells and always present in pairs contained within a structure known as centrosome found near the nucleus. A new matching set of us is made up in the process of division. One called a daughter centriole and the other called the mother centriole.
 We separate chromosomes during cell division by creating mitotic poles that cause these chromosomes to move away from one another and be pulled towards us with help of spindle fibers that extend from us towards the metaphase plate. Chromosomes wouldn’t separate without our pull, they would remain as one and in a group with other chromosomes thus resulting in impossibility of mitosis.  
Other jobs that would be impossible without us are intracellular transportation, motility, the maintenance of the structural integrity of the cell, and the formation of the cilia/flagella. Without us, asexual and sexual reproduction would not exist. Meaning that animals, such as humans would scientifically not be able to survive. This is true because without our help in cell division, cells would become too large which would prevent them from being able to function properly. The cell would eventually explode or break down and die because of this. Just like any other system would.  
 We are a great role player in the life of sperm cells as well. We are the ones that form the sperms tail. We give a sperm protein fibers that give them additional energy and a wavelike movement that drives them through the seminal fluid. If we were not here for the sperms use, they wouldn’t be able to navigate. On the contrary, they would be stuck in one place resulting in impossible contact with the female reproductive cell known as the egg. Both female and male reproductive cells are critical for reproducing multicellular life systems (sexual reproduction). This is because these two cells form an embryo when in contact which continues to grow in the women’s uterus concluding in baby being                                                                             made/born.
 In other words, you could very well say that we are the organelle making all animal life possible. After reading this you know that even small parts of the cell play the biggest roles so why vote for other organelles when you know the most important one is right here!!!!

  1. Centrioles may be important in animal cells, but what about plant cells? Can this really be considered the 'most important cell' if it is only present in one type of cell? Peroxisomes, however insignificant they may seem to you, are present in both, and do their job thoroughly in both. Also, seeing as how hardly any cells require flagellum, is this feature really important? Of course it's significant to the sperm cells, but does this really appeal to the other cells?

    In my opinion, other organelles such as the peroxisomes are much more important, seeing as how they protect the cell. Protection is very important, after all. -P. Peroxisome
