Microtubules and Microfilaments.
chromosomes
muscle cell
It is a strong structure (becuase it is a net of covalently bonded polysaccharides and peptides) which stops the cell it encloses from expanding too much, thus stopping it exploding.
Some cell that has to do with movement, since "kineto" means "movement" and "plast" is a cell.
Cell
It is called the cell wall.
muscle cell
Flagella are external structures that propel cells. The cytoskeleton (I believe actin and myosin are the components of the cytoskeleton responsible for movement, but I'm not sure) is an internal structure that facilitates movement by changing the shape of the cell.
The cytoskeleton is the supporting structure of the cell that is also involved in movement.

Cilia and Flagella.

The nucleues, the brain of the cell.
