Answer:

Meiosis1 occurs in the microspore mother cell which produces 2 diploid cells. After the meiosis2 the number of cells becomes four. The ploidy of each cell in a tetrad happens to have a ploidy 'n' as they are produced by the meiotic division. So the answer is: the ploidy of the cell of the tetrad is haploidy.

Answer:

Each and every cell in a microspore tetrad is haploid

Tetrad just means there are four cells all of which are haploid in nature and are formed by reduction division or meiosis in microspore mother cells.
