How Does Bread Mold Reproduce? Bread mold reproduces asexually, using mitosis to form spores, and sexually. Sexual reproduction involves contact between opposite mating strains of the fungus to form a zygospore. Bread mold, Rhizopus stolonifer, most often reproduces asexually. Reproduction begins soon after bread mold finds a suitable substrate ...
Rhizopus stolonifer grows primarily as mycelia, which consists of long filamentous cells, or hyphae, that lack cross walls, known as septa. The lack of septa enables the mold to be named coenocytic. Coenocytic means that the mold is a multinucleate cell enclosed by one cell wall that contains chitin. Asexual Reproduction
Rhizopus stolonifer is commonly known as black bread mold. It is a member of Zygomycota and considered the most important species in the genus Rhizopus. It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions. It is a common agent of decomposition of stored foods.
In sexual reproduction a bread mold reproduces when each parent contributes half of the DNA necessary to form the offspring a zygote appears as a result of sexual reproduction and when the two ...
ASEXUAL REPRODUCTION. The drawing at the left shows a close-up of the asexually reproducing Bread Mold Fungus shown above. Spores from sporangia are released, often to be carried away by the wind. If they land in a moist place they may germinate to form branching, white, fuzzy stuff called hyphae.
If left in a warm, dark and moist environment, bread may grow mold. Common bread molds are fuzzy and appear black or blue-green. Certain species of mold can kill bacterial infections. Causes Spores from mold floating through the air land on bread and activate when moisture and temperature conditions are right.
Rhizopus stolonifer: morphology and reproduction of black bread mold. Rhizopus stolonifer is also known as black bread mold. Thallus is white cottony, much branched mycelium. Mycelium is differentiated into nodes and internodes. The nodal region bears much branched rhizoid grows downward, inside the substratum for anchorage and absorption of ...
The Black bread mold, Rhizopus stolonifer, is a common type of fungus. It grows and reproduces the same way that most molds do. In asexual reproduction, the mold makes spores inside a sporangium. When the spores are ready to leave and spread more mold, the sporangium breaks open and lets the spores float out.
Molds reproduce by producing large numbers of small spores, which may contain a single nucleus or be multinucleate. Mold spores can be asexual (the products of mitosis) or sexual (the products of meiosis); many species can produce both types.
MOULDS AND THEIR CHARACTERISTICS. Moulds, those dusty little spots often found spreading over bread, cheese, books, and other things in the home, cause the loss of millions of dollars to our economy every year and, even worse, may be a menace to your health.
