A spore is a small reproductive unit capable of creating a new organism without sexual fusion. Spores differ from gametes since spores will germinate and develop into sporelings (haploid gametophyte), while gametes must combine to form a zygote before development. Spores play a role in the alternation of generations life cycle. In this life cycle, spores divide by mitosis and form haploid gametophytes. Gametes are produced, and unite to form a diploid zygote. The zygote develops into a sporophyte, which will produce more spores by meiosis to begin the cycle again. Spores can be seen under this leaf.
