microtubule
Cilia.
The cytoskeleton is a network of hollow tubes made of proteins called microtubules that provide support and maintain the shape of the cell. They are involved in various cellular functions such as cell division, intracellular transport, and movement.
Hollow tubes are cylindrical structures that have empty spaces or cavities inside them. They are commonly used in various applications, such as piping, structural support, and biological systems. Examples include straws, blood vessels, and plumbing pipes.
The organelle that consists of hollow tubes providing support for the cell is the cytoskeleton. It is made up of microtubules, microfilaments, and intermediate filaments that help maintain cell shape, facilitate cell movement, and allow for intracellular transport.
The cell's cytoskeleton, made up of microtubules and microfilaments, consists of hollow tubes that provide structure and support for the cell. These structures also play important roles in cell division, cell movement, and intracellular transport.
The microtubules that form centrioles and spindle fibers are made of tubulin protein subunits arranged in a tube-like structure. These hollow tubes provide structural support and play a crucial role in cell division by helping to organize and separate chromosomes.
Hollow tubes are used instead of solid steel tubes to reduce weight while maintaining structural strength. This makes them more cost-effective and efficient for various applications, such as construction, automotive and aerospace industries. Additionally, hollow tubes allow for easier passage of fluids, wires, or other elements through the center.
Someone on another qustion that was exactly like yours said microtubules, so I hope that helps you out (:
Stalagmites
A capillary is hollow. It is the smallest of the blood vessels, the tubes that carry blood.
