In most cases,the vegetative cell of a fungal hypha contains more than one nucleus,often hundreds of nuclei are present. Protoplasm Cell Wall Septum Even if a hypha has cross-walls,cytoplasmic movement is often not prevented,as there is usually a pore in the center of the septum through which nuclei and cytoplasmic particles can move

The morphology Reproduction Classification Typical species Filamentous fungi
The morphology of filamentous fungi The filamentous fungi consists of two parts:the mycelium and the spores. A typical hypha is a nucleated tube containing cytoplasm.Usually there is extensive cytoplasmic movement within a hypha,generally in a direc- tion toward the hyphal tip,and the older portions of the hypha usually become vacuolated and virtually devoid of cytoplasm. Each hypha is about 5-10 um wide

Reproduction Asexual spores are formed by the aerial mycelium of one organism.When these spores germinate,they become organisms that are genetically identical to the parent. Sexual spores result from the fusion of nuclei from two opposite mating strains of the same species of fungus.Organisms that grow from sexual spores will have genetic characteristics of both parental strains
