A diploid cell is a cell that contains two sets of chromosomes. One set of chromosomes is donated from each parent. The diploid number is commonly abbreviated as 2n. For humans this equation would be 2n=46. Humans have 2 sets of 23 chromosomes leading to a total of 46 chromosomes.

Haploid cell is a cell that has only a single set of chromosomes. The cell contains only one member of each homologous pair of chromosomes (haploid number = n). For example - A  human germ cell (a sperm or an egg cell) is haploid, which means it contains only one of each of the 23 chromosomes of the human genome, or it only has half the diploid (2n) number of a human somatic cell (which is 46).

The stagnation in the agricultural sector was caused mainly because of the various systems of land-settlement that were introduced

by the colonial government. Particularly under the Zamindari system, the profit accruing out of the

agriculture sector went to Zamindars instead of the cultivators. The Zamindars did nothing to improve the condition of agriculture. Their main interest was only of collect rent regardless of the economic conditions of the cultivators. This caused immense misery and social tension among the latter. Under Zamindari system, intermediaries (Zamindari) benefitted at the cost of both

actual cultivator and the state.

The polar nuclei are the two nuclei situated at the central position of the embryo sac. They together fuse with the male nucleus other than the one who fuses the egg. After fusion the polar nuclei form endosperm which acts as the food supply unit for the seeds in dormancy.
