What is Asexual reproduction? Asexual reproduction is the formation of offspring from a single parent.
The offspring are identical to the parent.
Types of asexual reproduction.
- Binary fission in amoeba.
- Spore formation in Rhizopus.
- Budding in yeast.
- This involves the division of the parent organism into two daughter cells.
- The nucleus first divides into two and then the cytoplasm separates into two portions
- Binary fission also occurs in bacteria, Paramecium, Trypanosoma and Euglena.
Spore formation in Rhizopus
- Rhizopus is a saprophytic fungus which grows on various substrate such as bread, rotting fruits or other decaying organic matter.
- The vegetative body is called mycelium which has many branched threads called hyphae.
- Horizontal hyphae are called stolons.
- Vertical hyphae are called sporangiophore.
- The tips of sporangiophore become swollen to form sporangia, the spore bearing structure.
- Each sporangium contains many spores.
- As it matures and ripens, it turns black in colour.
- When fully mature the sporangium wall burst and release spores which are dispersed by wind or
