Punnett Squares help with this. The heterozygous plant has two different alleles  one for tallness, the other for shortness. You are told that it is tall so you know that one tall allele is sufficient to confer tallness  that lets you sort out the dominance relationship. Tall is dominant to short. The short plant, therefore, is homozygous recessive. Your genotypes are Tt and tt. Doing a Punnett Square will give you the genotypes  which you can interpret as phenotypes  of the offspring. Hope that's helpful.
