Microtubules (actin and tubulin) are cytoskeleton of eukaryote (and not prokaryote). Prokaryote do have cytoskeleton system such as FtsZ.
what does prokayote mean
The Cytoskeleton is a system of microtubules, in a cell.
microtubules
Prokaryotes do not have a nucleus.
A bat is a multicellular organism made up eukaryotic cells.
Tigers are eukaryotes, as are all animals.http://dictionary.reference.com/browse/eukaryote
The kinetochore microtubules
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.
It is a cell lacking membrane bound organelles. includes all bacteria and archea
Yes, spindle fibers and microtubules are essentially the same in that spindle fibers are composed of microtubules. Microtubules are a component of the cytoskeleton, made of tubulin protein subunits, and they play various roles in cellular structure and transport. During cell division, specifically in mitosis and meiosis, microtubules organize into spindle fibers that help separate chromosomes. Thus, while all spindle fibers are microtubules, not all microtubules function as spindle fibers.
Flagella possess a central bundle of microtubules in which nine outer double microtubules surround a central pair of single microtubules. This characteristic "9 + 2" arrangement of microtubules is also seen in cilia.
Microtubules are polymers of tubulin. Microfilaments are polymers of actin.
