SURVIVAL  OF  PLANTS
Ë Plants also need to ensure the survival o their species.
Ë When the fruit of a plant is ripe, it either falls to the ground or splits open to release the seeds.
Ë If all the mature seeds falls straight down and germinate near the parent plaant will be crowded.
Ë Thus the young plants will have to compete or sunlight,water and mineral.
Ë To prevent this from happening,the seeds need to be adapted for dispersal.
Ë Dispersal means scattering or distributing the seeds to other places for germination.
Ë Different plants disperse their fruits and seeds in different ways.
Ë They are dispersed far and wide by agents such as:
·       Water
·       The wind
·       Animals
·       Explosive mechanism
