NEET BIOLOGY

Detailed explanation-1: -Hyphae called stolons grow across the surface of the food source and continue to add to mycelium.

Detailed explanation-2: -In mycology, a stolon is defined as an occasionally septate hypha, which connects sporangiophores together. Root-like structures called rhizoids may appear on the stolon as well, anchoring the hyphae to the substrate. The stolon is commonly found in bread molds, and are seen as horizontally expanding across the mold.

Detailed explanation-3: -Hyphae that have cross-walls are calledseptate, whereas those without cross-walls are referred to asaseptate. Some fungi that have septate hyphae also have aseptate or septate specialized hyphae (conidiophores) that bear asexual reproductive structures.
