In which simple multi-cellular organism does sporangia develop on hyphae and spore formation occurs in sporangia?
Yeast
Amoeba
Leishmania
Rhizopus
Rhizopus
Rhizopus, commonly known as bread mould, is a simple multicellular organism that reproduces via spore formation. During this process, specialized structures called sporangia develop on hyphae (thread-like filaments), where spores are produced and stored until they are released to grow into new organisms.
Rhizopus, commonly known as bread mould, is a simple multicellular organism that reproduces via spore formation. During this process, specialized structures called sporangia develop on hyphae (thread-like filaments), where spores are produced and stored until they are released to grow into new organisms.
Think of the sporangia as a 'dandelion head' full of seeds. Just as the dandelion releases its seeds to be carried by the wind to new locations, the bread mould releases its spores to travel and colonize new surfaces.
Rhizopus belongs to the Fungi kingdom. It consists of thread-like hyphae; when it reaches reproductive maturity, vertical hyphae (sporangiophores) grow upwards, developing a bulbous, sac-like structure at the tip called a sporangium. Inside the sporangium, the cytoplasm undergoes cleavage to form numerous tiny, resistant spores. When conditions are favourable, the sporangium wall bursts, dispersing the spores into the environment to germinate on organic matter.
Rhizopus is a saprophytic fungus commonly found on moist, decaying organic matter.
The reproductive phase involves the growth of sporangiophores bearing sporangia.
Spores are asexual reproductive units covered by thick, protective walls to survive adverse conditions.
Once released, spores germinate on suitable surfaces, developing new branched hyphae.
Allows rapid dispersal of progeny to distant locations via air currents.
Enables survival in harsh environmental conditions due to thick spore walls.
Biological reproduction study in Fungi.
Decomposition of organic waste materials.
Yeast (a unicellular fungus) typically reproduces by budding.
Amoeba (a protist) reproduces primarily by binary fission.
Leishmania (a flagellate protist) reproduces by longitudinal binary fission.
Option D is correct because Rhizopus is a classic example of a bread mould that utilizes sporangia for asexual spore formation.
D is correct тАФ Rhizopus is a multicellular fungal organism that reproduces by forming spores within specialized structures called sporangia.
Remember that while fungi like Rhizopus use spores, unicellular organisms like bacteria and Amoeba typically use fission, and budding is the trademark of yeast!
