Detailed explanation-1: -A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called “septa” (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells.

Detailed explanation-2: -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-3: -Septate hyphae of Aspergillus in lung tissue. Note the hyphae are compartmentalized by cross walls or septa.

Detailed explanation-4: -Ascomycota (sac fungi): Members of the subdivision Ascomycota include molds that have septate hyphae and some yeasts. They are called sac fungi because their sexual spores, called ascospores, are produced in a sac or ascus. Asexual reproduction is via conidiospores.

Detailed explanation-5: -Some fungi have hyphae divided into cellular compartments by walls called septa. Septa have tiny perforations which allow molecules, cytoplasm, and sometimes organelles to move between the cells. Fungi can close their septa if they are injured, preventing fluid loss from the rest of the filament.
