Definition for Septate hyphae
From Biology Forums Dictionary
Septate hyphae have dividers between the cells, called septa (singular septum). The septa have openings called pores between the cells, to allow the flow of cytoplasm and nutrients throughout the mycelium. Although the septa separate the cells, in some hyphae the cellular components, including the nucleus, can fit through the pores. When new cells bud at the apex of the hypha, a septum does not form immediately. As the new cell matures, the cell wall grows down into the cytoplasm, forming the septum. Members of the classes Basiodiomycetes and Ascomycetes form septate hyphae.
