With seed dispersal, the seeds will not be overcrowded with the parent plant. Seed Dispersal by Explosions. 1)First, seed survival is often higher away from the parent plant. That pollen travels to other flowers and fertilizes the ovary. This higher survival may result from the actions of density-dependent seed and seedling predators and pathogens, which often target the high concentrations of seeds beneath adults. There is a "top" seed, which sits along the curved, convex side of the bur, and a "bottom" seed that sits along the inner flat surface of the bur. ️The hard seed coats provide protection against injury.

Leads to overcrowding around the parent plant. Seed dispersal can be advantageous (1) in escape from density- or distance-dependent seed and seedling mortality, (2) by colonization of suitable sites unpredictable in space and time, and (3) by directed dispersal to particular sites with a relatively high probability of survival. The further the seed goes, the more likely more of them will grow and make it to maturity.
