Asexual reproduction means reproduction where one organism produces a genetically identical organism by itself.
Step 1. An airborne spore lands on a piece of bread, germinates into rhizoids and stolons. Rhizoids and stolons are just different kinds of hyphae. Rhizoids are the rootlike hyphae that penetrate the surface of the bread and stolons are the stemlike hyphae that run along the surface of the bread.
Step 2. Some of the hyphae grow into the air, creating sporangiophores.
Step 3. Sporangiums are produced at the top of the sporangiophores.
Step 4. Spores are produced within the sporangium.
Step 5. The sporangium matures and releases spores into the air.
Step 2. Some of the hyphae grow into the air, creating sporangiophores.
Step 3. Sporangiums are produced at the top of the sporangiophores.
Step 4. Spores are produced within the sporangium.
Step 5. The sporangium matures and releases spores into the air.
Sexual Reproduction Sexual reproduction means reproduction where two cells combine to form a genetically different organism. These cells usually come from two different organisms. Read through the following steps showing the sexual reproduction of Rhizopus stolonifer.
Step 1. Two hyphae, one positive and one negative, come together, forming a gametangia.
Step 2. The gametangia produce haploid gametes which combine to form a zygospore. A zygospore is a thick-walled zygote and is the structure from which this phylum gets its name.
Step 3. The zygospore germinates and grows into hyphae.
Step 4. The hyphae then grow and form a sporangium.
Step 5. The sporangium matures and releases spores into the air.
