Tubular filaments with cross walls found in large fungi are ___________.
a. Septate hyphae
b. Aseptate hyphae
c. Aseptate haustoria
d. Dimorphic mycelia

검증된 단계별 안내

Understand the structure of fungal hyphae: Hyphae are the thread-like filaments that make up the mycelium of a fungus.

Recall that hyphae can be classified based on the presence or absence of cross walls (septa) within the filaments.

Identify that 'septate hyphae' have cross walls (septa) dividing the filament into distinct cells, while 'aseptate hyphae' lack these cross walls and appear as continuous tubes.

Recognize that 'haustoria' are specialized structures used by some parasitic fungi to extract nutrients from host cells, and 'dimorphic mycelia' refers to fungi that can switch between yeast and filamentous forms.

Conclude that the term describing tubular filaments with cross walls in large fungi corresponds to 'septate hyphae'.

Hyphae Structure in Fungi

Hyphae are the thread-like filaments that make up the mycelium of a fungus. They can be either septate, meaning they have cross walls (septa) dividing the cells, or aseptate, lacking these cross walls and forming a continuous cytoplasmic mass.

Septate vs. Aseptate Hyphae

Septate hyphae contain septa that separate individual cells, allowing compartmentalization and controlled flow of organelles. Aseptate hyphae lack septa, resulting in a multinucleate, continuous cytoplasm, typical of some lower fungi like Zygomycetes.

Fungal Terminology: Haustoria and Dimorphic Mycelia

Haustoria are specialized hyphal structures used by parasitic fungi to extract nutrients from host cells. Dimorphic mycelia refer to fungi that can switch between yeast and filamentous forms depending on environmental conditions, unrelated to the presence of septa.

Tubular filaments with cross walls found in large fungi are ___________.a. Septate hyphaeb. Aseptate hyphaec. Aseptate haustoriad. Dimorphic mycelia
