I think the posters were a great idea.

I’m very proud of our teamwork in this poster and really happy with the way it turned out and our presentation :) ”
I accidentally removed the above post from Beth whilst trying to edit the page. Sorry, I thought your comments were so inspiring that I had to repost them, but unfortunately they appear now under my name! Apologies girls....... Keep up the fantastic work.. I was trying to do something fancy but it back fired..Oh well you learn from your mistakes!
Hey guys, I’ve had a bit of a read and my understanding of the centrosome in basic terms is that it’s an organelle within eukaryotic cells (so an animal cell), and is located in the centre of the cell in the cytoplasm, close to the nucleus. It consists of two CENTRIOLES, cylindrical in shape, which are made up of microtubules (referred to as the goods train in our analogy). They are orientated at right angles to each other. (Imagine musk sticks). Centrioles play a role in cell division where they divide and give microtubule growth which becomes the structures that chromosomes align to, or sit on, during cell division. They are also known as ‘basal bodies,’ which refers the structural base for cilia and flagella. Anybody, please correct me if I am wrong!!!
I think the 15mins we had with Sophie after biology today was really beneficial! Having it explained in a way to think of a cell in a flow chart format really helped!
So, the cytoskeleton! As we found out in our research for our presentation, I understand the cytoskeleton is literally the skeleton of the cell, it maintains the shape of the cell, but more importantly it's role is cell motility. I didn't realize how complex the cytoskeleton was until watching the you tube video by Harvard! It really puts it into perspective.
There are 3 protein filaments that make up the cytoskeleton: - mictotubles - intermediate filaments - microfilaments (Actin filaments)
The cytoskeleton is responsible for internal movements of organelles throughout the cell, and this is done on the microtubles by it's 'motors'. (remember the 'musk sticks' Alba referred to above!) During meisos and mitosis, the migration on chromosomes also takes place on the microtubles (then the spindle fibers are formed).
The microfilaments (also referred to as actin filaments) are found just beneath the plasma membrane. There are responsible for giving shape to the cell - they form a band and provide the mechanical strength to the cell.
The third filament is the intermediate filament, and, as the name suggests its size is in between the microtubles and microfilaments. From further reading, I found out there are different types of intermediate filaments. The main purpose of these filaments, again, is for maintaining the structure of the cell, and they support the microtubles as microfilaments.
All in all, the cytoskeleton is an incredibly complex system and without it a cell wouldn't be able to survive.
I hope all this information is accurate and helps everyone have a better understanding of the importance of the cytoskeleton in cells!

Yay im on!!
ReplyDeleteYay me too!
ReplyDeleteOk team, do you think you could tell us a little more about the centrioles?

Well done Alba. That is correct and I love your 'musk' analogy!
ReplyDeletePS.. if you like it would be nice to upload a photo of yourselves so that we don't always have to look at the Blogger icon.

Great work Alba :)

Beth, this is brilliant! Who can forget the cute myosin molecules carrying the protein along the microtubule in the video!!! Well done!!
