The structure surrounded by microtubules near the nucleus is the centrosome. The centrosome serves as the main organizing center for microtubules in the cell and plays a crucial role in cell division by helping to arrange the mitotic spindle. It typically consists of a pair of centrioles and the pericentriolar material, which aids in the nucleation and anchoring of microtubules.

What do microtubules radiate from?
Centrosome (centrum=center, soma=body) it lies near the nucleus helps maintain the shape of the cell & acts as tracks along which organelles can move Source: Bio Textbook Sylvia S. Mader
Where are centrioles found?
Centrioles are found in animal cells, typically in pairs near the nucleus. They play a key role in cell division by organizing the microtubules that form the spindle apparatus.
What do Centrosomes look like?
Centrosomes are typically spherical or oval-shaped organelles found near the nucleus of animal cells. They consist of two centrioles that are perpendicular to each other and surrounded by pericentriolar material. Centrosomes play a crucial role in organizing microtubules during cell division.
Is at the center of an atom and is surrounded by the?
Nucleus is at the center of atom. It is surrounded by electrons.
Where are originate the microtubules that form the mitotic spindle?
Microtubules that form the mitotic spindle originate from the centrosomes, which are found near the nucleus in animal cells. The centrosomes serve as the main organizing centers for microtubule assembly during cell division. Additionally, some microtubules can also originate from non-centrosomal sites in the cell.

In animal cells microtubules grow from which structure?
Microtubules grow from the microtubule-organizing center (MTOC), which is typically located near the cell nucleus. The MTOC serves as a major organizing site for the assembly of microtubules, providing the necessary environment for their formation and growth.
Where is nucleus found in a plant and an animal cell?
In a plant cell, the nucleus is typically found near the center of the cell, surrounded by cytoplasm and other organelles. In an animal cell, the nucleus is also located near the center, surrounded by cytoplasm and organelles. Both plant and animal cells have a membrane-bound nucleus that contains genetic material, such as DNA.
Two rod shaped bodies near the nucleus are called?
rod-shaped? The nucleus is filled with protons and neutrons, usually depicted as spheres. you are thinking of a nucleus in an atom (chemistry). in biology, the rod-shaped structures inside the nucleus is the chromosome, the genetic material of the cell.
What do Centrosomes look like?
Centrosomes are typically spherical or oval-shaped organelles found near the nucleus of animal cells. They consist of two centrioles that are perpendicular to each other and surrounded by pericentriolar material. Centrosomes play a crucial role in organizing microtubules during cell division.
Describe the arrangement of microtubules that compose the centrioles?
Centrioles are composed of nine triplets of microtubules arranged in a cylindrical structure. Each triplet consists of three microtubules, with one complete and two incomplete. The centrioles are typically found in pairs near the nucleus of animal cells and play a crucial role in cell division.
