Which of these are functions of the cytoskeleton?
It helps to maintain cell shape.
It provides a place for chemical reactions to occur.
It plays important roles in both the intracellular movement of substances and in cell division.
It holds organelles in place, and for some cells, it enables cell movement.
It creates new proteins, lipids, and other organic molecules
Which of these are cytoskeleton fibers?
microtubules
intermediate filaments
microfilaments
cytoplasm
microflagella
Cytosol is a watery, gel-like material that makes up much of the cytoplasm.
true
false
These are hollow cylinders and are the thickest of the cytoskeleton structures and most commonly made of filaments which are polymers of tubulin.
microtubles
intermeadiate filaments
microfilaments
cytoplasm
These are made of two thin actin chains that are twisted around one another. They are found in almost every cell, and are numerous in muscle cells and in cells that move by changing shape
microtubles
intermeadiate filaments
microfilaments
cytoplasm
