you should refer to a sliding microtubule model. in this model, there is a "9+2" structure or pattern, along with spokes, motor proteins and a basal body. the spokes connect to the 2 microtubules in the center and the motor protein, dynein, connects the 9 pairs to each other. dynein "walks" one microtubule pair relative to the other. if they weren't fixed in place at either end, they would move past each other. they are fixed at one end by attachment to the basal body, which is attacked just inside the plasma membrane. therefore the walking motion pulls the microtubule pairs over (while spokes contribute to the lack of free movement). keep in mind that dynein requires energy. it binds, releases and moves, binds, releases and moves. (think of a cat climbing a tree.)
What else can I help you with?
What structures allow for cell movement?
Cilia and flagella
Is cilia longer than flagella?
No itis not. Flagella are longer than cilia
Does flagella or cilia have a membrane?
Flagella and cilia do not have a membrane of their own. They are extensions of the cell membrane and are composed of microtubules. These structures help with cell movement and sensory functions in various organisms.
What type of movement euglena have pseudopodia flagella or cilia?
Euglina has flagella. Paramesium has cilia. Amoeba has pseudopods
Blepharisma have cilia or flagella?
Blepharisma have cilia, which are hair-like structures used for movement and feeding. Flagella are whip-like structures used for propulsion in some microorganisms, but Blepharisma primarily rely on their cilia for movement.

How do protozoans move'?
Protozoans move with the help Pseudopodia, cilia and flagella. Pseudopodia - Amoeba Cilia - Paramaecium Flagella - Euglena
Is cilia longer than flagella?
No itis not. Flagella are longer than cilia
Cilia and flagella move due to energy provided by the enzymatic breakdown of ATP by what?
The movement of cilia and flagella is powered by the ATP-dependent motor protein dynein, which hydrolyzes ATP to provide the energy needed for movement. Dynein is responsible for producing the sliding motion between microtubule doublets, causing cilia and flagella to bend and generate movement.
Cilia and flagella are cell surfaces structed adapted from what?
Eukaryotic cilia and flagella are cell surfaceprojections familiar to ....

Is the Stentor a Cilia or Flagella?
Stentor is a ciliated protozoan, meaning it has cilia for movement.
What three organelles enable eukaryotic cells to move?
The three organelles are cilia, flagella, and pseudopods. Cilia and flagella are structures that extend from the cell surface and help in cell motility, while pseudopods are temporary projections of the cell membrane used for movement in certain cell types.
Does flagella or cilia have a membrane?
Flagella and cilia do not have a membrane of their own. They are extensions of the cell membrane and are composed of microtubules. These structures help with cell movement and sensory functions in various organisms.
What type of movement euglena have pseudopodia flagella or cilia?
Euglina has flagella. Paramesium has cilia. Amoeba has pseudopods
Name three ways in which cilia and flagella differ?
Cilia are shorter and more numerous than flagella. Flagella typically have a whip-like motion, while cilia have a coordinated back-and-forth movement. Functionally, cilia are involved in moving substances along the cell surface, while flagella are used for cell propulsion.
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.
