Question

Are Deuteromycetes Septate or Aseptate?

Answer 1

Septation

1. Fungi have long thread-like filamentous structures called hyphae.
2. These vegetative structures comprise cells that are made of the chitin cell wall. They may or may not contain septa, which are perforated cross-walls.
3. Presence of septa in the fungal mycelium is called septate hyphae. The nucleated cells are separate. Due to the presence of perforations, cytoplasm and cell organelles move across the hyphae.
4. Example- basidiomycetes, ascomycetes, etc.
5. Absence of septa in the fungal mycelium is called aseptate hyphae. The cells are not distinctly separated, thereby the cells appear multinucleated. They are also called coenocytic hyphae.
6. Example- zygomycetes, etc.

Deuteromycetes:

1. They are commonly called molds, or imperfect fungi.
2. Examples- Colletotrichum, Trichoderma, Alternaria, etc.
3. Deuteromycetes have well-developed septate mycelium. The mycelium is branched profusely, cells are multinucleate, and septa have simple pores.
