In many plants, for example mosses, the haploid stage (called the gametophyte) is a complete independent organism with its own life span.  

In animals, the only haploid stages are when the parent animals produce gametes, the eggs or sperm.

a sporophyte, a diploid plant organism will undergo meiosis to form haploid spores...the spores will undergo mitosis to generate a multicellular-haploid organism called the gametophyte. the gametophyte will then undergo mitosis to form the gametes
the difference is that in humans, meiosis leads DIRECTLY to gametes. in plants, meiosis leads to the formation of spores, AND THEN gametes (so it is indirect).
