What is the difference between septate and aseptate hyphae

But, septa are not present in hyphae of all fungi. Coenocytic hyphae are nonseptate, also called aseptate, meaning they are one long cell that is not divided into compartments.

Coenocytic hyphae result from nuclear divisions within a cell without an accompanying division of the cytoplasm cytokinesis. Non-septate hyphae, also known as aseptate or coenocytic hyphae, form one long cell with many nuclei. While they do not form septa between nuclei, they do form a septum at branch points that connect one filament to another, preventing the entire network from being compromised if one hypha is injured.

Hyphae are found enveloping the gonidia in lichens, making up a large part of their structure. In nematode-trapping fungi, hyphae may be modified into trapping structures such as constricting rings and adhesive nets. There are two main types of hyphae. Septate hyphae have walls that separate individual cells, while coenocytic hyphae are one long continuous cell without walls.

Hyphae perform a variety of functions in fungi. They contain the cytoplasm or cell sap, including the nuclei containing genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus fungus body. In addition to budding yeast cells and pseudohyphae, yeasts such as C albicans may form true hyphae. Dolipore septa are specialized dividing walls between the cells septa which seperates cells within a hypha. These are found in the species of fungi Basidiomycetes.

They have a barrel-shaped swelling around their central pore. These allow the flow of cytoplasm, cell nuclei, mitochondria across the hypha. Such hyphae are called dikaryotic hyphae. The septa between the cells have each a central pore. The dolipore septal complex is, however, absent in the smuts. But, septa are not present in hyphae of all fungi. Hyphae that have walls between the cells are called septate hyphae; hyphae that lack walls and cell membranes between the cells are called nonseptate or coenocytic hyphae Figure 1.

The hyphae of most fungi are divided into cells by internal walls called septa singular, septum. Septa usually have little pores that are large enough to allow ribosomes, mitochondria, and sometimes nuclei to flow among cells. Hyphae that are divided into cells are called septate hyphae. There are three types of hyphae among fungi. Coenocytic or non-septated hyphae. Septate hyphae with uninucleated cell. Septate hyphae with multinucleated cell.

Hyphae are found enveloping the gonidia in lichens, making up a large part of their structure. In nematode-trapping fungi, hyphae may be modified into trapping structures such as constricting rings and adhesive nets.

Septate hyphae have dividers between the cells, called septa singular septum. Septate hyphae can completely close the septa if they are injured, preserving the integrity of the rest of the filament. The septa also provide increased structural stability for the hyphae. Based in Wenatchee, Wash.
