Sexual reproduction needs both male and female parts of plant.But there is also another way in which only one organism is required for multiplication and formation of new organisms.This is called asexual reproduction. New plants are obtained without producing seeds or spores. The various methods of asexual reproduction commonly found in plants are binary fission, spore formation, fragmentation, budding and vegetative propagation.
