Solution:

Colchicine is an alkaloid extracted from seed and corm of Colchicum autumnale. It has the property of arresting and breaking the spindle so that a cell division without cell wall formation may be affected leading to doubling of chromosome number. So a diploid cell will become tetraploid by chromosome doubling.
