No
No, septa of hyphal cross walls are not always present in fungi. Some fungi have continuous hyphae without septa, known as coenocytic fungi, while others have septa that divide the hyphae into compartments.
Hyphal cross walls are called septa. They are not always present in fungal hyphae, as some fungi are aseptate and lack these dividing structures.
Septae, which are cross-walls that divide the hyphae of fungi, are not always present in all types of hyphae. In septate fungi, these structures are common, providing structural support and allowing for the compartmentalization of cells. However, in aseptate fungi, such as those in the group Zygomycetes, hyphae are typically coenocytic, meaning they lack septa and consist of continuous cytoplasmic mass with multiple nuclei. Therefore, the presence of septa in hyphae depends on the specific type of fungus.
septa
There is no such number as septa nor septa zero.
Rhizpous hyphae are not divided, so are coenocytic.
