* Centrioles: These small, cylindrical structures are responsible for organizing microtubules, which form the spindle fibers that pull chromosomes apart during mitosis. They are found in animal cells and some protists but not in plant cells.
* Nucleolus: This structure within the nucleus produces ribosomes, which are essential for protein synthesis. During mitosis, the nucleolus disappears as the nuclear envelope breaks down.
* Chromosomes: These structures carry the genetic information of the cell in the form of DNA. During mitosis, chromosomes condense and are separated into two identical sets.
* Microtubules: These protein filaments form the spindle fibers that attach to chromosomes and pull them apart. They also play a role in separating the cytoplasm and forming the two daughter cells.
* Nuclear envelope: This membrane encloses the nucleus and breaks down during prophase, allowing the spindle fibers to access the chromosomes. It reforms around the chromosomes during telophase.
Therefore, mitosis is a complex process that involves the coordinated action of several organelles.
It's important to note that while centrioles play a key role in animal cells, plant cells don't have them. Instead, they have microtubule organizing centers (MTOCs) that perform a similar function.
