Which of the following has a 9 2 arrangement of microtubules?
Cilia
Cilia, which are used for motion, have a 9+2 arrangement of microtubules.
What is meant by 9 plus 2 arrangement of microtubules?
The 9 + 2 arrangement refers to how the microtubules are organised in structures such as the flagella and cilia. It has 9 pairs of microtubules situated on the outside that are bound together and 2 pairs of microtubules in the middle that are not bound together.
What is the 9 2 arrangement of the microtubules in the cilia known as?
Flagella and cilia consist of 9 fused pairs of protein microtubules with side arms of the motor molecule dynein that originate from a centriole. These form a ring around an inner central pair of microtubules that arise from a plate near the cell surface. The arrangement of microtubules is known as a 2X9+2 arrangement.
Which of the following contain the 9 2 arrangement?
Answer: Both flagella and cilia have a 9 + 2 arrangement of microtubules.
Do Centrioles have a 9 2 arrangement?
-Eukaryotic flagella and cilia share a common structural organization of 9+2 arrangement. Here, nine doublet microtubules are arranged peripherally surrounding a central pair of singlet microtubules. But they differ in length, number per cell, and even the beating pattern. So, the correct answer is ‘Centrioles.
Where do you find the following arrangement of microtubules?
Microtubules are nucleated and organized by microtubule organizing centers (MTOCs), such as the centrosome found in the center of many animal cells or the basal bodies found in cilia and flagella, or the spindle pole bodies found in most fungi.
Which of the following structures has a 9 2 arrangement of microtubules quizlet?
Like cilia, eukaryotic flagella have a 9 2 arrangement of microtubules covered by the cell’s plasma membrane. A membrane-enclosed structure with a specialized function within a cell.
Do cilia have a 9 2 arrangement?
Cilia depend on their highly differentiated structure, a 9 + 2 arrangement, to remove particles from the lung and to transport reproductive cells.
What contains the 9 2 arrangement of microtubules consisting of nine doublets of microtubules surrounding a pair of single microtubules?
motile cilium
The motile cilium is a complex organelle that is typically comprised of a 9+2 microtubule skeleton; nine doublet microtubules surrounding a pair of central singlet microtubules.
Which of the following contains the 9 2 arrangement of microtubules quizlet?
Which of the following contains the 9 2 arrangements of microtubules consisting of 9 doublets of microtubules surrounding a pair of single microtubules?
What is the microtubule arrangement of a flagellum or cilium quizlet?
Both flagella and cilia have a common structure and mechanisms of movement. Both are composed of microtubules wrapped in an extension of the plasma membrane. Contain a ring of nine microtubule doublets surrounding a central pair of microtubules. This arrangement is called 9 + 2 Pattern.
How are the 9 2 pattern of microtubules arranged?
The 9 + 2 arrangement refers to how the microtubules are organised in structures such as the flagella and cilia. It has 9 pairs of microtubules situated on the outside that are bound together and 2 pairs of microtubules in the middle that are not bound together. Furthermore, how are microtubules arranged?
How many microtubules are in the axoneme of flagella?
Inside cilia and flagella is a microtubule-based cytoskeleton called the axoneme. The axoneme of primary cilia typically has a ring of nine outer microtubule doublets (called a 9+0 axoneme), and the axoneme of a motile cilium has two central microtubules in addition to the nine outer doublets (called a 9+2 axoneme).
Which is the organizing center of the microtubule?
In fact, in animal cells, the centrosome is the microtubule-organizing center. In eukaryotic cells, flagella and cilia are quite different structurally from their counterparts in prokaryotes, as discussed below.
Where are microtubules and intermediate filaments found in a cell?
Microtubules are found in the interior of the cell where they maintain cell shape by resisting compressive forces. Intermediate filaments are found throughout the cell and hold organelles in place. Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest.
