THE BORN OF EUCARIOTIC CELLS

Diposkan oleh Rosmana A.P. Saturday, August 15, 2009

Cells are the smallest part of organisms body. These things are the structural and functional unit in organisms. There're several types of cell. For example procariotic and eucariotic cells which divided based on the existation of membrane which cover the cell's nuclear. A cell will be classified as eucariotic cell if it have cell's nuclear membrane. If not, this cell will be classified as procariotic cell.

There're still many mysteries about cells. Especially cells mysteries which have relation with the origin of lives. One of them is the hypothesis about the origin of eucariotic cells which estimated come from procariotic cells. This hypothesis appears because the mystery of the lives origin that can't be solved.

This hypothesis said that eucariotic cells comes from procariotic cells. This is because there're many organeles and membrane structure that eucariotic cells have show similarities to whole procariotic cells structure. These similarities are estimated as the tranformation traces from procariotic cells into eucariotic cells. One of these traces is the cell's nuclear membrane. This nuclear membrane is said come from the cell's membrane which "fold" into it's inner cell. This folding maybe happens to protects the genetic substance which contained in the nuclear area in procariotic cells. As the evidences, you can see the nuclear membranes which show that these membrane are duplex (double membranes). Beside that, there's Endoplasmic Reticulum which said as the trace of the nuclear membranes formation.

Why Endoplasmic Reticulum said as the trace of the nuclear membranes formation? It because this organele connects the cell's nuclear and the environment outside cell. So, that's why this organele estimated as the trace of the formation of nuclear cell.

Beside this trace, there're Mitochondria and Plastide (Chloroplast) that also estimated as the traces. Mitochondria is an organelle which work as the place for cell's respiration. Plastide (Chloroplast) is an organele where photosynthesis take place. Plastide can be found only in photosynthetic cells.

Mitochondria and Plastide are estimated as a procariotic organism in the past. It because these organeles show similarities with procariotic organism. For example, the outter membrane of mytochondria which almost same with the nuclear outter membrane that estimated as the folding to the inner part. Even, Mitochondria has it's own DNA which really different with the nuclear's.

The formation of mitochondria and plastide are estimated start from an anaerobic eucariotic cell that "gulp" an aerobic procariotic cell by phagocytosis. After "gulped", this procariotic cell isn't diggested. But, become a kind of endosymbion that simbiote with it host (anaerobic eucariotic cell). This symbiosis gives benefits to these cells and cause they become unseparateable. Then, the aerobic procariotic cell become mitochondria and the anaerobic eucariotic cell become aerobic eucariotic cell.

That is the hypothesis of mitochondria origin. This hypothesis almost same with the hypothesis of plastide origin. The different is only the kind of procariotic cell that was gulped. If the mitochondria origin was estimated as aerobic procariotic cell. The plastide origin was estimated as photosynthetic procariotic cell. But, is this hypothesis right? No one know about it.

  13. i am not quite understand about biology or cells, cuz when i was still in high school, i never payed attention to this subject. so far, the info is good, keep going

     
  14. bamz Says:
  15. nice info dude, keep share !

     
  16. gomel Says:
  17. wow..
    biology,so interesting! i love biology..
    well, basicly, bedanya eukariot sama prokaritik kan ada atau tidaknya membran sel.. kalo di manusia, ya eukariotik karena mempunyai membran sel..
    nice info!
    jangan lupa mampir n komen balik yaa..ada yang baru :D

  61. hm... just realized that i've not left any comments on this post.
    hm.. while studying this topic, i forgot to ask what the origin of eucariotic cell is.

    hm... is there any possibilities that eucariotic cells is evolution from procariotic ?
    Hm.. *thinking*

    will ask my friend on DNA institution and will let you know.
