Practice question

Filamentous fungi body consists of thread-like hyphae collectively forming mycelium representing vegetative thallus responsible for growth and absorption. Individual hyphae grow apically extending via Spitzenkorper vesicle supply center delivering cell wall precursors, branching to explore substrate efficiently. Mycelium can be extensive covering hectares in Armillaria. Single hypha denotes filament, sporangium is asexual spore container, ascus is sexual meiosporangium with ascospores. Mycelium performs nutrient absorption, anchorage and often perennial growth, while reproductive structures emerge from it under environmental triggers. Septal pores regulated by Woronin bodies and associated proteins prevent cytoplasmic loss upon wounding, enhancing hyphal survival and compartmentalized aging.
