Are microtubules found in eukaryotic cells or prokaryotic cells?
Microtubules are found in Eukarytotic cells. However, some archeabacteria have been found to contain microtubule-like structures but these are not true microtubules.
Does bacteria have microtubules?
Bacteria do not have microtubules in an eukaryotic sense since they do not have tubulin. However, they do have tubulin homologue FtsZ protein that form structures and perform functions similar to microtubules in eukaryotes. Sometimes these structures are referred to as 'bacteria microtubules'.
The cytoskeleton helps give a cell shape What structures plays this role?
Microfilaments and microtubules
What roadways of the cell move materials?
The primary roadways of the cell that move materials are the cytoskeletal structures, specifically microtubules and actin filaments. Microtubules serve as tracks for motor proteins, such as kinesin and dynein, which transport cellular cargo along them. Actin filaments play a crucial role in cellular movement and transport processes, facilitating the movement of vesicles and organelles. Together, these structures ensure efficient distribution and transportation of materials within the cell.
What makes up the structures of centrioles basal bodies cilia and flagella?
Centrioles, basal bodies, cilia, and flagella are primarily composed of microtubules, which are cylindrical structures made of tubulin protein. Centrioles consist of a specific arrangement of nine triplets of microtubules, while basal bodies serve as the anchoring structures for cilia and flagella, consisting of nine pairs of microtubules arranged in a circular pattern. Cilia and flagella have a core structure called the axoneme, which typically features a "9+2" arrangement of microtubules—nine doublets surrounding two central singlets. These structures play essential roles in cellular movement and the organization of the cytoskeleton.
What structures make up the fibers of the mitotic spindle?
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.
What is tiny structures in animal cells that help to organize microtubules?
centriole
Is a microtubules a plant or an animal?
No. They are structures found in plant and animal cells.
What structures are present in the animal cells that were not present in the plant cells?
-Centrosomes -Microtubules
What structures carry out cell movement?
a. cytoplasm and ribosomes b. nucleolus and nucleus c. microtubules and microfilaments d. chromosomes answer is c. microtubules and microfilaments

Is actin a microtubule or are they distinct structures within the cell?
Actin and microtubules are distinct structures within the cell. Actin is a protein that forms thin filaments, while microtubules are made of tubulin proteins and form a network of hollow tubes. Both actin and microtubules play important roles in cell structure and movement.
What is the description of microtubule?
The description of microtubules is hollow rods or hollow cylindrical structures. They mainly help to shape and support the cell.
