Spores are produced by bacteria, fungi, algae, and plants. Bacterial spores serve largely as a resting, or dormant, stage in the bacterial life cycle, helping to preserve the bacterium through periods of unfavourable conditions.

What organisms use spores to reproduce?

Spores are reproductive cells in plants; algae and other protists; and fungi. They are typically single-celled and have the ability to develop into a new organism. Unlike gametes in sexual reproduction, spores do not need to fuse in order for reproduction to take place.

What spores are asexually produced?

Sporangiospores are asexual spores formed inside a walled sporangium. Sporangiospores include the spores of zygomycetes, which are exposed to air by splitting of the mature sporangial wall, and motile zoospores of chytrids expelled into water from their zoosporangia.
