Ploidy of root tip cells
Webbpolyploidy, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.

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.
