cytockeleton provides shape, support and movement to cells.
It attaches the organelles into its network made out of protein
fibers. There are several types of fibers, thin micro-filaments,
intermediate filaments, and thick microtubules. They provides
4 important functions:
shape is determined by these filaments if the cell has no
movement is caused by the assembly, disassembly
and sliding of these mico-filaments
movement is caused by the microtubules and microfilaments
Cell division the microtubules pull the chromosomes into
the daughter nuclei. In animal cell division a ring of microfilaments
pinch off the parent cell around the middle to separate the
cytoplasm into tow parts.
