one of two small cylindrical cell organelles composes of nine triplet microtubules, which form the asters during mitosis.
A structure in the cell that plays an important role in cell replication. During prophase, the centrioles migrate to the poles of the cell and form the mitotic spindle, which allows the chromosomes to be organized and split when the cell divides.
Paired cellular organelle which functions in the organization of the mitotic spindle during cell division in eukaryotes.
either of two organelles that appear early in prophase of cell division. This organelleis composed of nine peripheral triplicates of microtubules and two central paired microtubules. This organelle gives rise to spindle fibers that form the spindle apparatus during late prophase, metaphase and anaphase.
a structure composed of microtubules that gives rise to the mitotic spindle (which is also composed of microtubules); not found in plant cells
Either of two cylindrical structures within the centrosome of animal cells and containing nine sets of triplet microtubules; structurally similar to a basal body. (Figure 19-5b)
A minute cell organoid within the centrosome.
a cylinder-like organelle that assists in chromosomal migration during mitosis.
A pair of small cylindrical structures each about 0.2 micron in diameter and 0.4 micron long, that lie at right angles to one another; present at each pole of the mitotic spindle in animal cells and in some other eukaryotes.
A cylindrical intracellular organelle composed of nine groups of microtubules, three in each group; functions in mitosis or meiosis by organizing the microtubules of the spindle apparatus.
Short cylindrical array of microtubules, closely similar in structure to a basal body. A pair of centrioles is usually found at the center of a centrosome in animal cells.
a cylindrical structure within the cell that plays a part in cell reproduction
an animal organelle that directs the movement of chromosomes during mitosis and is involved in spindle formation
a small organelle found in animal cells
a small set of microtubules arranged in a specific way
A short cylindrical organelle, found in pairs arranged at right angles to each other at the centre of a microtubule organizing centre (MTOC) or centrosome, found in eukaryotes (except in higher plants). A centriole is similar in structure to the basal body found at the base of eukaryotic cilia and flagella and organises the axoneme, the bundle of microtubules and other proteins forming the core of each cilium or flagellum. The centrosome organizes formation of a spindle during mitosis or meiosis.
One of two structures in the center of animal cells, composed of cylinders of nine triplet microtubules in a ring. Centrioles help organize microtubule assembly during cell division
Centrioles are cellular organelles that are found more often in animal cells. Centrioles lie next to the nucleus and are important during cell division.
A cylindrical structure made from a series of 9 paired microtubules that is involved in organization of microskeletal elements in the cells of animals and some plants. The centriole found just beneath the surface of a eukaryote flagellum or cilium is called a basal body while the perpendicularly paired centrioles found near the nucleus during interphase of animal cells is sometimes called the central body(centrosome). The centriole is encountered during discussions of mitosis and meiosis.
The cellular structure from which microtubules radiate in the mitotic spindle involved in the separation of chromosomes in mitosis.
One of a pair of cellular organelles that occur especially in animals, are adjacent to the nucleus, function in the formation of the spindle apparatus during cell division, and consist of a cylinder with nine microtubules arranged peripherally in a circle.
Organelle in cells which is made of microtubles
A centriole in biology is a barrel shaped microtubule structure found in most animal cells and algae though not frequently in plants. The walls of each centriole are usually composed of nine triplets of microtubules, although Drosophila embryos have nine doublets and Caenorhabditis elegans sperm cells and early embryos have nine singlets. An associated pair of centrioles, spatially arranged at right-angles, constitutes the compound structure known to cell biologists as the centrosome.
