Introduction to fungal spores
Members of the kingdom Fungi reproduce by vegetative means, asexually by spores (conidia, sporangiospores, zoospores) and sexually by oospores, ascospores and basidiospores.
Aplanospores
Aplanospores are non-motile spores produced asexually by Mucor fungi. These spores are produced endogenously in sporangia during favourable environmental conditions.
