. . Spore Formation Even in many simple multi-cellular organisms, specific reproductive parts can be identified. The thread-like structures that developed on the bread in Activity .
above are the hyphae of the bread mould ( Rhizopus ). They are not reproductive parts. On the other hand, the tiny blob-on-a-stick structures are involved in reproduction. The blobs are sporangia, which contain cells, or spores, that can eventually develop into new Rhizopus individuals (Fig.
. ). The spores are covered by thick walls that protect them until they come into contact with another moist surface and can begin to grow. Figure .
