Microtubules are long, cylindrical structures made up of tubulin protein subunits. They are arranged in a polarized fashion with one end called the "plus end" and the other end called the "minus end". Microtubules can organize into various configurations within cells, such as forming a radial array around the centrosome or serving as tracks for intracellular transport.

What are strings that hold together the centrioles?
Centrioles are held together by protein filaments called microtubules. The microtubules are arranged in a specific pattern to form the cylindrical structure of centrioles. These structures play a key role in organizing the microtubule network in the cell and are involved in cell division.
What does centrioles consist of?
Centrioles consist of microtubules arranged in a specific pattern known as a 9+0 or 9+2 arrangement. They play a crucial role in organizing the microtubule network during cell division and are involved in the formation of cilia and flagella in eukaryotic cells.
What is a short cylindrical assembly of micro tubules arranged in nine groups of three micro tubules is called?
A short cylindrical assembly of microtubules arranged in nine groups of three microtubules is called a "basal body." Basal bodies serve as the organizing centers for the formation of cilia and flagella in eukaryotic cells, anchoring these structures and facilitating their movement. They are structurally similar to centrioles, which also play a role in cell division.
What is a nine fused microtubule at the core of an animal centrosome?
A nine fused microtubule at the core of an animal centrosome refers to a structure called a centriole. Centrioles are cylindrical arrays of microtubules arranged in a 9+0 pattern, meaning there are nine triplets of microtubules in a circle with no central microtubules. Centrosomes play a vital role in organizing the microtubule cytoskeleton and are involved in processes such as cell division and cell motility.
What is the complex assembly of micro-tubules that occur in pairs?
The complex assembly of microtubules that occurs in pairs is known as a "doublet." These doublets are primarily found in structures like cilia and flagella, where they play a crucial role in cellular movement. In these structures, nine pairs of microtubules are arranged in a circular pattern, with two additional microtubules in the center, forming a characteristic "9+2" arrangement. This configuration is essential for the motility and functionality of these organelles.
What makes up cilia flagella and centrioles?
Cilia and flagella are made up of microtubules arranged in a 9+2 pattern, which consists of a central pair of microtubules surrounded by nine doublets. Centrioles are also composed of microtubules arranged in a 9+0 pattern. These structures play essential roles in cell motility and division.
What forms centrioles?
Micro tubules build up centrioles.There is a pair in an animal cell.
The electron microscope has revealed that one of the components within the cell consists of microtubules arranged to form a hollow tube This structure is a?
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.
What are cilia and flagella made up of?
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
What are centrioles composed of?
Centrioles are composed of microtubules arranged in a specific pattern, typically in a cylindrical shape. They play a key role in organizing the microtubules of the cytoskeleton and are essential for cell division.
What long hairlike projection on cells is composed by pairs of microtubules?
Cilia are the long hairlike projections on cells that are composed of pairs of microtubules arranged in a 9+2 pattern. They are involved in cell motility and sensing the external environment.
What has slender tubes that provide movement in cilia and flagella?
Axoneme is the slender tubes that provide movement in cilia and flagella. It is made up of microtubules arranged in a specific pattern that generates the whip-like motion of these cellular structures.
Describe the arrangement of microtubules that compose the centrioles?
Centrioles are composed of nine triplets of microtubules arranged in a cylindrical structure. Each triplet consists of three microtubules, with one complete and two incomplete. The centrioles are typically found in pairs near the nucleus of animal cells and play a crucial role in cell division.
What are strings that hold together the centrioles?
Centrioles are held together by protein filaments called microtubules. The microtubules are arranged in a specific pattern to form the cylindrical structure of centrioles. These structures play a key role in organizing the microtubule network in the cell and are involved in cell division.
What does centrioles consist of?
Centrioles consist of microtubules arranged in a specific pattern known as a 9+0 or 9+2 arrangement. They play a crucial role in organizing the microtubule network during cell division and are involved in the formation of cilia and flagella in eukaryotic cells.
Which cytoskeletal element has the thickest diameter?
Microtubules have the thickest diameter among the cytoskeletal elements, measuring about 25 nanometers in diameter. They are composed of tubulin subunits arranged in a hollow tube structure. Microtubules are involved in many cellular processes, including cell division and intracellular transport.

A short cylindrical assembly of microtubules arranged in nine groups of three microtubules is called a "basal body." Basal bodies serve as the organizing centers for the formation of cilia and flagella in eukaryotic cells, anchoring these structures and facilitating their movement. They are structurally similar to centrioles, which also play a role in cell division.
