Do you find in relation relationship between the weight of the seeds and the dispersal magnesium discuss with suitable examples
Answers
Seed dispersal is the transport or movement of seeds from plants with the help of biotic or abiotic agents. Plants have limited movement and, therefore, rely on various factors for the dispersal of seeds. The main methods are gravity, wind, ballistic, water and the help of animals.
The weight of the seeds is definitely a factor in the way it is dispersed. Coconuts or jackfruits bear heavier seeds; left to themselves, the seeds would drop straight down under the influence of gravity and germinate close to the mother tree. On the other hand, cotton seeds are lighter; after the pods burst open under the ballistic mechanism, they would disperse over a wider area. Some seeds or fruits cling to the furry coat of mammals and disperse widely.
In view of the above, the lighter seeds naturally spread over wider areas, generally using wind, sometimes water, as the transporting medium
