What condition arises if karyokinesis occurs without cytokinesis?

$A$ student observed a plant cell from a field in the telophase stage. He informed his teacher that the cell appeared different from other cells in telophase. The formation of the cell plate was not observed. Consequently,the cell contained a higher number of chromosomes compared to other dividing cells. This phenomenon results in $..........$.

$A$ cell plate is laid down during

Which of the following structures is the base for defining the formation site of the cell plate at the end of nuclear division?

During which phase are organelles like mitochondria and chloroplasts distributed equally between the two daughter cells?

In animal cells,where does the constriction of the cytoplasm begin during cytokinesis?
