What is the difference among sexual spores and gametes? Do humans present sexual spores or gametes?
Sexual spores are structures formed from meiosis with ploidy (number of chromosomes) reduction to a half compared to the spore mother cell. Spores germinate and give existence to gametophytes, individuals that by mitosis form gametes. The meiosis that forms sexual spores is called as sporic meiosis; it is, for instance, the type of meiosis that happens in plants.
