When a metatarsal bone, a bone connecting the toe to the rest of the foot, is involved, pain will be felt in the upper foot. Metatarsal Bone Spurs-A bone spur in one of the metatarsals often coincides with a presence of arthritis in the area, and both the spur and the arthritis may require treatment.
Haploid organisms such as fungi, yeast, and algae can have complex cell cycles, in which the choice between sexual or asexual reproduction is fluid, and often influenced by the environment. Some organisms, in addition to their usual haploid state, can also exist as diploid for a short time, allowing genetic recombination to occur.
Haploid spores grow into cottony tangles of hyphae called mycelia. These mycelia usually grow under the surface until they meet up with another mycelium. The two join (plasmogamy) and produce a series of binucleate, dikaryotic hyphae that reach above the ground and form the fruiting body or basidioma.
