In resting spores, germination involves cracking the thick cell wall of the dormant spore. In slime molds, germination refers to the emergence of amoeboid cells from the hardened spore. The multicellular diploid sporophyte produces structures called spore capsules. One spore forms per one vegetative bacterium. In mycology, it is the liberation of a fungal spore. These two cells in addition to the spore wall make up an immature pollen grain. Female sporocarps are much smaller, containing one sporangium and one functional spore. The resulting zygote germinates into a resting spore. The life of a hornwort starts from a haploid spore. Therefore, nearly all truffles depend on mycophagous animal vectors for spore dispersal. Conditions necessary for spore maturation differ among species. Scanning electron microscopy reveals reticulations on the spore surface. The free gills are white, as is the spore print. Maxis is best known for its simulation games, including "The Sims", "Spore" and "SimCity". Gametophytes, as with all heterosporous plants, develop within the spore wall.
