Spore Formation : In spore formation, the parent plant produces hundreds of tiny spores which can then produce new plants. During the growth of a fungus plants like. Rhizopus, tiny round bulb like structure called sporangium develops at the top of the hyphae.
Non-flowering plants like fungi (mucor, Rhzopus, penicillium) bacteria, ferns or mosses, formation of spores is method of reproduction.
Regeneration :¬ It is the ability of an organism to replace its lost body parts.
A special case of regeneration is fragmentation, in which a parent multicelluar organism on maturing breaks up naturally to produce two or more daughter organisms.
Among plants, filamentous algae like spirogyra reproduce by this method.
Hydra, Planaria & Sponges exhibit regeneration.
