Someone on another qustion that was exactly like yours said microtubules, so I hope that helps you out (:
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.
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.
Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant.
Peristalsis is the progressive wavelike movement that occurs involuntarily in hollow tubes of the body, such as the digestive system. It helps propel contents through these tubes, like food through the esophagus or waste through the intestines.
Xylem tissue is responsible for transporting water and minerals from the roots to the rest of the plant. It consists of specialized cells that form tubes to facilitate the movement of fluids. This process helps provide nutrients and support for the plant's growth and development.

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.
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 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.
Stalagmites
A capillary is hollow. It is the smallest of the blood vessels, the tubes that carry blood.
The phloem consists mainly of sieve tubes, companion cells, phloem fibers, and parenchyma cells. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function. Phloem fibers provide structural support, and parenchyma cells store nutrients.
