The correct option is Both 1 and 2.
Explanation
Bread mould, scientifically known as Rhizopus, is a multicellular fungus. It reproduces asexually through the formation of spores. The body of the fungus is composed of a network of fine filaments.
Statement 1 is Correct: The thread-like structures that spread over the surface of the bread are called hyphae. These constitute the vegetative part of the fungus (mycelium) and are responsible for anchoring the organism and absorbing nutrients from the substrate. They are not reproductive parts.
Statement 2 is Correct: The "blob-on-a-stick" structures observed at the tips of erect hyphae (sporangiophores) are called sporangia. These are the reproductive structures. Inside each sporangium, numerous spores are produced. When the sporangium bursts, these spores are released and can germinate to form new individuals under favourable conditions.
Key Takeaway: In spore-forming fungi like Rhizopus, the hyphae serve as the vegetative structure for growth and nutrition, while the sporangia act as the reproductive organs containing spores.
