Microtubules provide strength and support in tree trunks. Microtubules are long, strong fibers that are laid out in all directions in the cell's cytoplasm. They give the cell its shape and act as a tiny cell skeleton, providing strength and support.
In the brain, they are called glial cells.
the skeletal system supports our body structure and provides a framework the muscles use to cause movement.

Cartilage
The cytoskeleton provides internal support for plants and animal cells. They are made up of micro-tubules and micro-filaments that maintain the shape and give support to the cell.
The spicule in a sponge is its skeleton. It provides strength in the sponge.
Cellulose
As a matter of fact, the cytoskeleton provides a large degree of support to the cell
