Question

A cell at telophase stage is observed by a student in a plant brought from the field. He tells his teacher that thiscell is not like other cells at telophase stage. There is no formation of cell plate and thus the cell is containing morenumber of chromosomes as compared to other dividing cells. This would result in:

Accepted Answer

(b) [Key Concept: Polyploidy — Failed Cytokinesis] If no cell plate forms at telophase (failed cytokinesis) despite successful chromosome segregation (karyokinesis), the cell will have MORE than the normal number of chromosomes — both complete chromosome sets remain in one cell. This results in POLYPLOIDY — the cell has two complete sets of chromosomes in one nucleus (doubled). The chromosomes were properly distributed but cytokinesis failed, resulting in a nucleus with 4n instead of 2n chromosomes. Polyploidy from mitotic failure is common in plants.
