Meaning of cytoskeleton: earlier idea of cell was that it was a collection of some cell organelles suspended in cell sap but with the advancement of microscopic techniques and the discovery of electron microscopy the idea of cell has been changed radically. The cytoskeleton also plays an important role in mitosis, or cell division mitosis occurs in eukaryotic cells, and is the process by which two identical daughter cells form from a single parent cell mitosis is split into five phases: prophase, prometaphase, metaphase, anaphase, and telophase in the anaphase of mitosis, microtubules play an important role by helping the migration of.
