Labelled diagram of Spore formation in Rhizopus
Labelled diagram of Spore formation in Rhizopus: Spore formation is a method of asexual reproduction in which reproductive cells called spores are enclosed in sacs called sporangia. Spores mature inside the sporangium.
When the sporangia rupture, the spores are dispersed to grow on a new substratum. Under the right conditions, they develop into new plants.
The substratum is the surface to which the cell is attached, especially when the cell is growing. The thread like structures are hyphae.
They are not reproducible parts. Specific reproductive organs can also be identifies in many simple multicellular organisms.
The thread-like structure that forms on the bread is the hyphae of a bread mold called rhizopus. They are not reproducible parts.
On the other hand, small blob-on-a-stick structures are involved in reproductions. Blobs are sporangia, containing cells or spores, which can eventually develop into new Rhizopus individuals.
Spores are covered with thick walls that protect them until they come into contact with another moist surface and can germinate.
