Septate hyphae are hyphae that are subdivided into individual cells by

• A. Transverse walls
• B. Intercalary walls
• C. No walls
• D. Staggered partitions

Answer: (A)

Septate hyphae are divided into individual cells by cross walls called transverse septa. These walls run perpendicular to the hypha’s long axis and often have a septal pore that lets cytoplasm and organelles move between cells. This is what creates the segmented, cell-like units along the filament. In contrast, hyphae without walls lack these septa, and the others listed don’t describe the standard cross-walls that define septate hyphae.
