Which of the following statements are true? (i) Some cells in the adult animals do not appear to exhibit division. (ii) Many cells of animals divide only occasionally. (iii) These cells that do not divide further exit G₁-phase to enter an inactive stage called G₀. (iv) Cells in quiescent stage remain metabolically active but no longer proliferate unless called on to do so. (v) In animals, mitotic cell division is only seen in the diploid somatic cells. (vi) Plants can show mitotic divisions in both haploid and diploid cells.

How many statements are true for telophase? (i) Centromeres split and chromatids separate. (ii) Chromatids move to opposite poles. (iii) Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. (iv) Nuclear envelope assembles around the chromosome clusters. (v) Nucleolus, golgi complex and ER reform. (vi) The individual chromosomes can no longer be seen and chromatin material tends to collect in a mass in the two poles.

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