Expert Answer
Dispersal by wind - Seeds of certain plants develop wing-like hairy structures which allow them to be carried away by wind. Plants like maple, Moringa (drum stick), Calotropis (milk weed), etc. Once mature and dry, they burst open and release seeds which are dispersed by wind.
Dispersal by explosion - Fruits of plants like pea, bean, castor, etc burst open once they are ripe thereby scattering the seeds in all directions. This mechanism is also referred as ‘explosion’.
