Spore formation is the method of developing new individuals by forming reproductive structures called spores.
A spore is a small spherical or oval structure which protects the future individual in a thick protective covering. Spore germinates on a substratum under favourable conditions. Some organisms like ferns, some groups of fungi reproduce by spore formation.
Advantages of spore formation
*A spore can withstand adverse conditions like high temperature, low moisture etc without getting spoiled. Under favourable conditions, spores can germinate into new individuals
*Spores can also be carried away easily by agents like wind water etc.
*The organism forming spores can propagate its species by protecting the future individual in a hard thick covering called as spore.
