WebApr 28, 2024 · Telophase is the final stage in cell division. During telophase, the nuclear envelopes reform around the new nuclei in each half of the dividing cell. The nucleolus, or ribosome producing portions of the nucleus return. As the cell has finished moving the chromosomes, the main parts of the spindle apparatus fall depolymerize, or fall apart. 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.
