What is the cytoskeleton made of?
Answers
The cytoskeleton is made up of microtubules,actin filaments and intermediate filaments.
Have you ever seen the scene in Harry Potter when the bone in Harry's arm is made to disappear? Without a bone, his arm starts bending and flapping around like rubber. That's because, without a skeleton, there's nothing to keep our shape intact.
Cells also need to have something to keep their shape intact, a cytoskeleton. In fact the word cyto means 'cell,' so the cytoskeleton is the cell's skeleton. Put another way, the cytoskeleton is the framework of the cell. It is highly organized and also flexible. It doesn't appear the same as our skeleton, but some parts of it can act like our bones, and some parts can act like our muscles.
Eukaryotic cells contain a complex network of protein fibers called the cytoskeleton. It forms a framework for the movement of organelles around the cytoplasm - most of the organelles are attached to the cytoskeleton. The network consists of protein microfilaments, intermediate filaments, and microtubules.
