A cell weighing

1 mg

grows to double its initial mass before dividing into two daughter cells of equal mass. Assuming no death, at the end of 100 divisions what will be the ratio of the mass of the entire population of these cells to that of the mass of the Earth? Assume that mass of the earth is

10^{24} kg

and

2^{10}

is approximately equal to 1000.

A cell at the 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 the telophase stage. There is no formation of the cell plate and thus the cell is containing more chromosomes as compared to other dividing cells. This would result in:
