function of a centriole?

[biochick]

K yall I’m stuck on my advanced biology homework. What is the function of a centriole? 😯

[biochick]

if there is anyone there please help

[Poison]

It has function in cell division. It is an organell found in pairs in animal cells.

PS: maybe you can try to use the dictionary.

[Morris]

Centrioles are a part of an organell that generates mitotic spindle: spindle is very important for a correct chromosome division between the to cells.

Hey biochick, are you doing advanced higher? SO am I 😀 he he :p
If you are you must be from Scotland like me? yeah? anyway, you already have your answer so I can’t really contribute here. Nice top meet you. 😀

[helplessinBio]

so ur saying that a centrolie has a function in cell division and what is mitotic spindle ❓ ❓ ❓ ❗ ❗ 😥

[helplessinBio]

ur doing this on advanced bio im in normal high school bio and i have to do a project on all of the organelles in the cell, and its due tomarrow

[helplessinBio]

sorry that was for biochick

[helplessinBio]

no offense or nothin

To help you to undestand what is mitotic spindle, I insert an image.

As you can see, splinde is in black: is formed by microtubules that start from centrioles and attack to chromosome’s centre (a microtubule for chromosome);in this image you can see a cell in metaphase; nucleus isn?t here and choromosomes can be easly seen.

thanks for the help morris

I am a Middle School student and even I know what a centriole is.

[MrMistery]

are you sure you do?
Current models have been unable to find what is it exactly that centrioles do. plant cells not have centrioles and they can generate spindles just fine. if you remove the centriols from an animal cell with a microlaser, a spindle will nevertheless form. this is not to say that centrioles are useless. nothing is useless. but we don’t really know what they do. our best guess is that they "somehow" help direct the spindle against the axis of the cell.

[moviestarmoi]

centrioles: produce the microtubules of cilia & flagella & microtubules that form the spindle during cell division.

[MischelS]

Thanks for providing links,they are very helpful.
I am also shearing something about function of a centriole.
Centrioles line up the chromosomes inside the cell and then they pull the chromosomes apart during cell replication.
Structure – nine triplets of microtubules form one centriole
– two centrioles form one centrosome

Function – forms spindle fibres to separate chromosomes during cell
division.

@michealS
you are nearly right save the part of Mr.Mistery’s comment

check if 2 centrioles form 1 centrosome

[jwalin]

centrosome is the region where the centriolles are contained

note: its the region

you could use a dictionary

that’s good
but didn’t the question ask the function 🙄 ❓
but anyways when i was in the middle school even i knew what a centriole and it’s function (for cell division) but never knew how? 😡
and another thing i never boasted 🙄 . but it’s okay. when the questioner asked he meant to even know the finer details. i hope;)

@MrMistery
wow
that’s new to me. (most of things are new to me as am just in 12th you know and learning)
can you ellaborate

Here’s an excellent resource on the possible role of centrioles in cellular intelligence:

http://www.basic.northwestern.edu/g-bue … llint0.htm

From what I know about the topic, a cell can divide without centrioles but cannot develop into an animal due to loss of migration behavior that makes their cells so much more "alive" in comparison to a vegetable that can do fine without a pair of them to help divide the cell and other things:

[kk]

Centrioles also orient in the direction of cell migration during interphase (when the cell is not dividing).

[sara135]

Centriole is a structure found in eukaryotic animal cells. Plant cells and fungi do no contain centrioles. Centriole is the part of the cell, which acts as the center for producing microtubules, which are the component of cytoskeleton. Cytoskeleton is the skeleton of the cell that provides both shape and structure to a cell. Animal cells contain 2 centrioles, which together form the structure, centrosome. In other words, the centrioles are found within the centrosomes, which is a small region in the cytoplasm near the nucleus. Within the centrosomes, the two centrioles are positioned in such a way that both are perpendicular to each other. Like other structures of a cell, centrioles too perform several important functions. Below here is a brief discussion about the centriole function and structure in the study of biology.

[nebeyuasrat]

it is one of the organells in a cell which generates exoskelleton(mitotic spindle in the process of cell division) in our cell which are part of the mitotic and miosis process

i recently read that even in mitosis the mitotic spindles don’t have an impact meaning that even if there is no mitotic spindle the chromosomes will migrate to opposing poles (i am assuming that you know what is going on in cell division)
