Mitosis require microtubules because they bind to the chromosomes and pull them to each pole of the cell. The cell can then divide with the respective chromosomes on separate halves of the cell.
prophase, metaphase, anaphase, telophase
This phase of mitosis is called metaphase. During metaphase, the microtubules from opposite poles of the cell attach to the centromeres of the chromosomes. The microtubules then exert force to align the chromosomes at the center of the cell, forming the metaphase plate.

Microtubules attach to kinetochores during the prometaphase stage of cell division. This attachment is essential for the proper alignment and segregation of chromosomes during mitosis.
Microtubules attach to kinetochores during prometaphase of mitosis, forming the mitotic spindle apparatus. This attachment is crucial for proper chromosome alignment and segregation during cell division.
Yes, centrosomes play a crucial role in organizing the microtubules that form the mitotic spindle, which helps separate chromosomes during mitosis. However, some cells can undergo mitosis without fully functional centrosomes, using alternative mechanisms for spindle formation.
microtubules or cytoskeleton (as in centrioles)
Most of the activity during mitosis occurs in the nucleus, where the duplicated chromosomes condense, align, and separate. The microtubules that form the spindle apparatus and help in chromosome movement also play a key role in mitosis. Additionally, the cytoplasm is involved in providing the necessary cellular components and energy for the process to occur.
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.

Mitosis must occur in budding.
This phase of mitosis is called metaphase. During metaphase, the microtubules from opposite poles of the cell attach to the centromeres of the chromosomes. The microtubules then exert force to align the chromosomes at the center of the cell, forming the metaphase plate.

Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
