They don't "know" anything. Evolution is not like spending experience points in a video game to level up their Seed Size stat. Rather, mutation and random combinations of genes through the shuffling of sexual reproduction resulted in different results. The ones which tended to help the plants reproduce, like by making a seed a local animal carried to favorable locations tended to survive and those with genes which negatively impacted their odds of reproducing tended to not pass on their genes.
