Why the mode of pollination in maize is cross-pollination? Why it is important to cover the ear shoot with a butter paper bag before the emergence of silks? What could be the consequences if a few silks emerge before bagging? (Marks4)

Its advisable to cover the ears as shot may enters or fly in air.

Explanation:

The cross-pollination is a type of pollination n which the sperm-laden pollen is a transfer from one cone of flower of one plant.  This created flowering in plants. Wheat is a self-pollinated crop and for cross foliation to take place what florets must be opened. This is done to allow for genetic diversity and is only available for short peroid of time. Once the skills are viable they make already to be contaminated with foreign pollen and its vital that ears are bagged before the process. As the consequences could be that pollen might fly away.
