Question

which out of the following reproduces by spore formation?
1 .spirogyra
2.bread mould
3. rose​

Answer 1

• Bread mould reproduces by spore formation. Black bread mould may be common sort of fungus. It reproduces and grows within the same way.
• The mould develops spores within a sporangium during agamogenesis.
• Spores are the asexual reproductive bodies. Spores does not seeds. In the spore formation method of reproduction, the parent plant produced hundreds of tiny spore in spore.
• The tiny spore of bread mould plant( Rhizopus fungus) are almost always present in air. If we keep a moist slice of bread for few days, then the spores of bread mould plant present in air settle on the moist slice bread and germinate to form new bread mould plants.
• The common bread mould plants consists of fine , thread -like projections called hyphae and thin knob-like structure called sporangia at the top.
• When the spores case bursts, the tiny spores are dispersed in air. These spores are the asexual reproductive bodies of bread mould plants which can produces more bread mould plants under suitable conditions.
