Answer 1

Depending on the fruit there are a few benefits.

It can nourish the seed with the nutrients, or it can encourage spread.
If an animal wants to eat the fruit, but cannot digest the seed, then the seed is passed through the animal and pooped out somewhere else. This would spread the seed farther than just falling off the plant.
