Which of the 9 2 arrangement of microtubules consists of nine doublets of microtubules surrounding a pair of single macrotubules?
The arrangement of microtubules described consists of nine doublets of microtubules surrounding a pair of single microtubules in the center. This arrangement is known as the "9+2" structure, found in eukaryotic flagella and cilia. It provides structural support and aids in the movement of these cellular structures.
What are the one or two hairlike structures that extend from the surface and help move the cells?
Cilia and flagella are the hairlike structures that extend from the surface of cells and help in cell movement. Cilia are short and numerous while flagella are longer and usually found singly or in pairs.
What are the characteristics of cilia and flagella?
Cilia and flagella are both hair-like structures found on cells that are involved in movement. Cilia are shorter and more numerous, while flagella are longer and usually found singly or in pairs on a cell. Both cilia and flagella contain a core of microtubules arranged in a 9+2 pattern that provides support and drives movement.
What is the macromolecule that builds both cilia and flagella?
The macromolecule that builds both cilia and flagella is primarily tubulin, which forms microtubules. These microtubules are arranged in a specific pattern, typically a "9+2" arrangement in eukaryotic cells, providing structural support and enabling movement. Additionally, proteins such as dynein and kinesin play crucial roles in the movement of cilia and flagella by facilitating the sliding of microtubules against one another.
What are organs of motility in protists you have learned about?
Some protists use cilia, flagella, or pseudopods for motility. Cilia are short, hair-like structures that beat in a coordinated manner to move the cell. Flagella are longer whip-like structures that propel the cell forward. Pseudopods are temporary bulges of the cell membrane that extend and contract to push the cell in a particular direction.
How do the cilia and flagella of protists differ from those of bacteria?
Cilia and flagella in protists are structurally more complex and composed of microtubules arranged in a 9+2 pattern, while bacterial flagella are simpler and made of a single protein called flagellin. Protist cilia and flagella also have a different beating pattern and are involved in various functions like locomotion and feeding, whereas bacterial flagella primarily aid in movement.
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.
How do cilia and flagella use the cytoskeletal components?
Cilia and flagella use the cytoskeletal components called microtubules to provide structural support and enable motility. Dynein motor proteins along the microtubules generate the bending movements that allow cilia and flagella to beat and move fluid or propel cells.
Is flagella longer and more numerous than cilia?
Flagella are longer and fewer in number compared to cilia. Flagella typically range from 10-200 micrometers in length and there are usually one to a few present per cell. Cilia, on the other hand, are shorter (usually 2-10 micrometers) and there are typically numerous cilia per cell.
Which of the following contain the 9 plus 2 arrangement of microtubules?
Cilia and flagella contain the 9+2 arrangement of microtubules in their structure. This arrangement consists of nine peripheral microtubule doublets surrounding two central microtubules.
Cells would be unable to form cillia or flagella if they did not have what?
Cells would be unable to form cilia or flagella if they did not have microtubules. Microtubules are a component of the cytoskeleton that provide structural support and facilitate the movement of cilia and flagella.

Cilia and flagella are the hairlike structures that extend from the surface of cells and help in cell movement. Cilia are short and numerous while flagella are longer and usually found singly or in pairs.
What other structures of the cytoskeleton would show the same pattern of microtubules as a flagellum?
Cilia, which are similar to flagella in structure, would also show the same pattern of microtubules. Both flagella and cilia contain a 9+2 arrangement of microtubules, with nine outer doublet microtubules and a central pair of microtubules.
What are the characteristics of cilia and flagella?
Cilia and flagella are both hair-like structures found on cells that are involved in movement. Cilia are shorter and more numerous, while flagella are longer and usually found singly or in pairs on a cell.

What contain the 9 2 arrangement of microtubules 1. cilia 2. centrioles 3. flagella 4. a and c only 5. a b and c?
#4. Both cilia and flagella use the 9+2 arrangement to generate movement. The centrioles gives rise to the microtubules, then it remains below the finished array as a basal body. centriole has 9+0 arrangement starting from basal body
