How do plant cells form spindle fibers
WebOne difference between cell division in plants and animals is that plant cells form a cell wall after mitosis to separate the nuclei and cytoplasm of the two new identical cells. After animal cells undergo mitosis, the cell membrane pinches together along along a cleavage furrow during cytokinesis. WebJul 26, 2024 · Aberrant centrosome activities in mutants of Dictyostelium discoideum result in anomalies of mitotic spindles that affect the reliability of chromosome segregation. Genetic instabilities caused by these deficiencies are tolerated in multinucleate cells, which can be produced by electric-pulse induced cell fusion as a source for aberrations in the …
