Question

define spore formation​

Answer 1

Explanation:

the parent plant produces hundreds of reproductive unit called spores when the spore case of plant burst then the spores spread into air . under favourable conditions they germinate and produce new plant

for example : rhizopus , mucor (fungi) , ferns ,, mosses (bread mould)

if we keep a moist slice of bread aside for few days then the spores of bread mould plant present in air settle on moist bread and germinate to form new plant it looks like white cottony mass covering bread slice which later turns into black .

it consists of :

*Fine thread like production called hypae

*Thin stem

*Knob like structures called sporongia (contain hundred of minute spores)

*These spores are sexual reproductive units which can produce more bread mould plants

*This method is used by unicellular as well as multicellular organism
