    Ive got a biology essay to do which asks How is the structure of cells related to its function?

    Im looking at muscle cells, so could any1 just give me a few pointers. SO far all i can come up with is the increased number of mitochondria.

    Any help is much appreciated.

    Ah yes, I've forgotten most of that crap. But you can say how it's one long sarcoplasm (I think) rather than different cells next to each other as the point of the cells joining would be a weak point. Then you got myofibrils, actin and **** like that. Sorry if that seemed vague, I've forgotten most of it, just google the stuff man.

    Thanks for your help. I have googled for ages, but it seems to always get too complicated. Im trying to find out i think how their structure is related to their function.

    the guy above is rite, its easier to google it. your gonna need to make an illustrated diagram of a muscle cell, then try to desrcibe the main features. im pretty sure any food text book will be able to help more and if not then google, text book is best

    High concentration of mitochondria in muscle cells - they will be using lots of energy so plenty of energy is required via respiration - respiration takes place in mitochondria - more mitochondria = more energy!

    Edit: Haha ~ didn't realise you had mentioned mitochondria. Long and fibre like - Muscle cells contain long, thin myofibrils. Myofibrils are made up of actin and myosin. These proteins enable muscles to contract or expand by sliding over each other.

    There's the sarcoplasmic reticulum in there, suppling Ca+? ions for the trypomyosin, so it moves and the actin filaments can attach to the myosin heads, power stroke ect.

    yep so write about how mitochondria help with respiration by producing ATP form the phosphulate (spelt maybe wrong) gland. You can also write about general terms such as nuclei, RER, SER, Golgi, Ribosomes, Membranes, Lysosomes. And then just link in how it is useful. E.g. Lysosomes contain enzymes to destroy a cell etc...Therefore if the muscle cell were to become damaged and weak then the lysosome could release the enzymes to destroy it.

    he, seeems like you need to know about specialised cells. So basically you just neeednto research this on websites. Specialised cells include sperm cells, so their shape of the head helps them break into the egg, they have an enzyme in the tip of the head which breaks down the egg, they have a tail to swim and because is requires a lot of energy is needs a lot of mitochondria. Another example is chloroplast, it has lots of chlorphyll for photsynthesis, is is a long rectangular shape so light rays hit it efficiently, it has a thick cell wall made of cellulose for rigidity, and the structure of the cellulose is branched so it is a firm molecule.

    but something like that, just look at specialised cells on google or something. hope this helps

    Knew someone would explain it better than I.
