Reproductive parts: The tiny blob-on-a-stick structures are the reproductive parts of Rhizopus. The blobs are called sporangia, which contain spores. These spores can develop into new Rhizopus individuals.
Non-reproductive parts: The thread-like structures called hyphae are the non-reproductive parts of bread mould.

The question directly maps to the textbook passage in 7.2.6. Examiners expect students to use the correct scientific terms: hyphae (non-reproductive) and sporangia/spores (reproductive). A common mistake is calling the whole "blob-on-a-stick" a spore — be precise: the sporangium is the blob (structure), and spores are the cells inside it. Mentioning that spores are covered by thick walls is a bonus but not required for full marks here.
