Get Movin' and Vote for the Cytoskeleton!!
WHAT IS IT?
A muscle and a skeleton.
WHAT DOES IT DO?
Is responsible for cytokinesis, cell movement, and the organization of the organelles within the cell.
WHY DO I CARE?
Oh.. you better. If you didn't have me, you wouldn't be able to have me as a "track" for the chromosomes to move during mitosis. Which means that if the chromosomes don't complete mitosis and you don't have the help from me to actually divide the cell during cytokinesis, then you wouldn't be here. Cells need to be able to divide or injuries would never heal, you would never grow, and lets be real here-- you wouldn't exist!
OKAY..... What else???
-It provides movement and stability to the cell.
-The cytoskeleton consists of microtubules, actin filaments, and intermediate filaments.
Microtubules
- acts as a frame to determine cell shape.
- provides a set of "tracks" for cell organelles and vesicles to follow.
- forms the spindle fibers for separating chromosomes during mitosis.
Actin Filaments
-they associate with the proteins that control muscle contractions within the cell.
-carry out cellular movements including gliding, contraction, and cytokinesis.
Intermediate Filaments
-provide flexible strength for the cell.
SO WHEN YOU'RE VOTING, VOTE CYTOSKELETON!! AND REMEMBER--WITHOUT ME YOU WOULDN'T EXIST!!!
The cytoskeleton isn't the only organelle that we have to thank for cytokinesis! Before cytokinesis, there must be mitosis, right? First, the nuclear membrane has to disappear to allow the chromosomes to duplicate (in prophase). If that didn't happen, the cytoskeleton would basically be rendered useless in that department, since mitosis would not be able to happen. There would be no need for the cytoskeleton to provide a track for the chromosomes. If the nuclear membrane didn't reappear in telophase, the cytoskeleton would have no need to divide the cell into two.
ReplyDeleteAnd as for providing stability to the cell, the cell wall or the cell membrane provides the same support to the cell.
The cytoskeleton provides an internal stabilization to the cell - while the cell wall and cell membrane provide capsulation for all the contents of the cell. The cytoskeleton holds the cell up, and allows motor proteins to literally walk along it's lines.
DeleteEven Earth (yes our planet) has cytoskeleton. wrap your mind around that for a second.
DeleteActually, without be providing inner support to you, and the rest of the organelles, you wouldn't be able to properly function. The cell wall and cell membrane provides outer support to keep the contents of the cell in. But if I wasn't there to literally support the contents of the cell, your job would be absolutely useless due to not being able to function properly because of lack of inner cell support and sending off what you need to other organelles in order to make the cell function. Without me, the function of your cell is pointless.
ReplyDeletefor all of you people if this was missing you wouldn't be there either
