The structures that act as the scaffolding for chromosomal attachment and movement are the spindle fibers. These are achromatic filaments that inwardly extend from the poles of a dividing cell.
Mitotic Spindle which forms between the centrioles, and the asters ("stars"), which radiate outward from the ends of the spindle and anchor it to the plasma membrane. The spindle acts as a scaffolding for the attachment and movement of the chromosomes during later mitotic stages. Meanwhile, the nuclear envelope and the nucleus break down and disappear.
spindle fibers and microtubules that attach to the kinetichores during miosis
Spindle? Those little microtubules that originate from centrioles... or so I think.
cytoskeleton
The spindle is the structure that acts as a scaffolding for chromosomal attachment and movement. This occurs during later mitotic stages.
There is no simple answer to this question :D
the hairlike structure that has the capacity for movement in bacteria is filia
The cytoskeleton helps a cell keep its shape. The internal movement of organelles, as well as cell locomotion and muscle fiber contraction couldn't take place without it.

Sort of. It certainly houses the cells responsible for the manufacture of both white and red blood cells - namely the bone marrow. But the skeleton also provides a structure, an attachment point for muscles and a leverage point for movement.

Spindle acts as a scaffolding for chromosomal attachment and movement. Chromosomes attach to the spindle fibers by undivided structures called centromeres.
Chromosomal movement is present throughout the cell division, but the first prominent movement is when the cell is in metaphase where the chromosomes move to line up at the middle of the cell.
Muscles work by either contracting or relaxing. The movement that they cause is dependent on the structure that they are attached to e.g contraction of the biceps causes the arm to bend upwards due to the attachment of ligaments.
chromosomal Translocation
They help in cell division, chromosomal movement , ciliary and flagellar locomotion .

The cytoskeleton is the supporting structure of the cell that is also involved in movement.
