Q. What is the difference between sexual gametes and spores? Do humans present sexual gametes or spores?

Sexual spores are structures generated from meiosis with ploidy number of chromosomes reduction to a half compared to the spore mother cell. Spores germinate give existence to gametophytes individuals that by mitosis form gametes. The meiosis that generates sexual spores is called sporic meiosis it is, for instance, the type of meiosis that occurs in plants.

Gametes are also cells with half the number of chromosomes of the normal cell of the species but they are specialized in fecundation the fusion with another gamete that generates the zygote a cell with double the number of chromosomes than gametic cells. Mitosis in gametophytes originated from sexual spores or by Gametes can appear from gametic meiosis.

In humans as well as largely in animals the meiosis is gametic. There are no alternations or spores of generations. The female gamete is the egg cell and the male gamete is the sperm cell.
