Over 70,000 species of living fungi have been identified.
Diploidy is transient, haploidy is the norm.
Nutrients are then absorbed. Cross walls are present for strength, and these are perforated so that cytoplasm is continuous from cell to cell. Fungal spores disperse from the parent and germinate into new mycelia. There are about 600 species of bread molds, e.g., Rhizopus . The hyphae lack cross walls.
