These are a type of hyphae, which are aseptate, which means they do not contain septa or a long cell that is not divided into compartments.
This type of hyphae is found in Zygomycota (bread molds).
These hyphae are a result of nuclear divisions within a cell without accompanying the division of the cytoplasm.
As a result, they possess several nuclei scattered around the cytoplasm along with the other cell organelles such as the endoplasmic reticulum, Golgi apparatus, and ribosomes.
