microtubules
Microtubules are the cytoskeleton fibers that are straight hollow tubes of protein. They are made up of tubulin protein subunits and play a crucial role in various cellular processes such as cell division, intracellular transport, and cell shape maintenance.
Spindle fibers are thin hollow cylinders that assist in chromosome movement during cell division. These structures are made of microtubules and help separate the chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
Thin hollow cylinders made of protein that provide structural support for eukaryotic cells are microtubules. Microtubules are involved in nuceic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
microtubules
Spindle fibers, also known as microtubules, are hollow protein fibers involved in the movement of chromosomes during cell division. These fibers form the spindle apparatus, which helps separate the chromosomes and pull them to opposite ends of the cell during both mitosis and meiosis.
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.

Microtubules are the cytoskeleton fibers that are straight hollow tubes of protein. They are made up of tubulin protein subunits and play a crucial role in various cellular processes such as cell division, intracellular transport, and cell shape maintenance.
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
Spindle fibers are thin hollow cylinders that assist in chromosome movement during cell division. These structures are made of microtubules and help separate the chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
The spindle on a lathe is made hollow primarily to reduce weight and improve the machine's overall balance and stability during operation. A hollow design also allows for easier access to the interior for maintenance and lubrication, as well as the capability to pass through longer workpieces or tools. Additionally, a hollow spindle can facilitate the use of various attachments and accessories, enhancing the lathe's versatility.

The structure described is a centriole. Centrioles are cylindrical structures made up of microtubules arranged in a specific pattern, forming a hollow tube. They play a crucial role in organizing the microtubules during cell division and are involved in the formation of spindle fibers.
Centrioles contain a pinwheel array of 9 triplets of microtubules to form a hollow tube. They play a role in organizing the spindle fibers during cell division and in the formation of cilia and flagella.
