ShareIn biology, a spore is a reproductive structure that is adapted for dispersion and surviving for extended periods of time in unfavorable conditions.

Spores form part of the life cycles of many plants, algae, fungi and some protozoans. Spores are usually haploid and unicellular and are produced by meiosis in the sporophyte.
Once conditions are favorable, the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which will eventually go on to produce gametes.
Two gametes fuse to create a new sporophyte.
This cycle is known as alternation of generations.
Haploid spores produced by mitosis (known as mitospores) are used by many fungi for asexual reproduction.
