A researcher has developed two stains for use with seed plants. One stains sporophyte tissue blue; the other stains gametophyte
sukhopar [10]

Answer:

A) The pollen grains will be pure red.

Explanation:

Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).  

In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte).  When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.

Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.
