Detailed explanation-1: -1) Septate hyphae-In most of the fungi the hyphae are divided into cells with the help of internal walls. These are called the septum. The septa are porous walls that allow the organelles like ribosomes and mitochondria to move in between the cells.

Detailed explanation-2: -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.

Detailed explanation-3: -Septate hyphae of Aspergillus in lung tissue. Note the hyphae are compartmentalized by cross walls or septa. Ascomycete hyphae are multi-nucleate and compartmentalized by septa with simple pores, i.e., all cytoplasmic contents including nuclei may flow up and down the hyphal strand.

Detailed explanation-4: -The key difference between septate and aseptate hyphae is that septate hyphae have septa or cross walls that divide hyphae into distinct cells while aseptate hyphae lack septa. Hyphae are long filament or thread-like structures of fungi. Hyphae represent the vegetative structure of fungi.
