This is quite interesting, I believe. It is basically a result of the fact that plants are sessile, meaning couch potatoes, and animals are mobile. Plants don't mind being sessile until they need to disperse their seeds to far away places, so evolution has come up with many strategies to disperse their seeds. The famous tumbleweed in western movies simply cuts itself loose from its roots and blows all over the plains, sowing seeds everywhere it goes. Dandelions attach a little parachute to each seed, to the delight of small children. Maples try the helicopter route, while cockleburrs and other similar plants use stickers to attach their seeds onto animal fur to hitch a ride. Impatiens slingshot their seeds into the air. But one of the best ways is to entice an animal to EAT your seeds, enclosing them in a very hard seed coat that is impervious to digestive juices, so they pass right through the animal. They are then deposited on the ground far away, complete with a little pile of fertilizer as well, to help the little seedlings get off to a really good start!! Fruit is a bribe, to entice us animals to disperse their seeds!

It is an incentives for animals to help spread their seeds.
All the fruits contains the seeds of the tree. It can be a big pit or small seeds.

When animals picks the fruits, some will carry the fruit with them. When they finish the fruit, the seed will be displaced in the different area from the mother tree.

To reproduce far away from the parent tree.

Let's take an apple tree for example.

It grows its fruit and say a deer walks by and eats one. The seeds inside are tough little buggers and they survive its digestive tract. Then when the deer is miles away it does its business *wink* . . .

Not only does this provide for the new sappling to be out of the shade of the parent tree where it can get some sun, but it is free fertilizer too!

The fruit attracts birds, insects, other animals, etc. The critters consume the fruit, seeds and all, and then pass the seed through their digestive system in a place away from where the fruit grew. The process coats the seed in a fertilizer enabling it go grow. The meat part of the fruit acts much like a seedpod similar to a pecan or walnut.

Good luck!

Some fruit trees are result of generation long genetic selection and enting - some trees produce fruit because mankind adapted them to produce fruit. For example, In their original version, apple trees were producing some kind of small, sour applet. Crossbreeding and selection resulted in cultivars that produce sterile supermarket apples like goldens, cox, fuji etc.. The original fruit were not sterile, and had some eatable outer layer, to attract animals to eat them, and dispose the containing seeds through their faeces in some other place, thus helping to spread out that specie. So..fruit trees produce trees because they believe it is a way to spread out their seeds.

They are too young. Have patience. They will need bigger pots unless they are on a dwarfing root stock. You need really to know how big they are expected to grow, and this all depends on what kind of rootstock they are grafted onto. I'd ask your supplier how old the trees were, how big they get and whether they will grow happily in tubs or need to go into the ground.You can't expect any fruit in the first year or the second - it does depend on how old the trees were when you bought them. My damson tree is now about 12 feet high and although it has flowered twice it still only has two damsons on it.

This type of trees contain flowers, and from the flower there is a pistil (where eggs are made) and a stamen(which makes pollen). Once the pollen is spread by insects or wind, It reaches the pistil and then travels to the ovary. This ovary is fertilized and in time gets bigger. By this time it is considered a fruit , then you enjoy your fruit!! The cycle continues as the seeds are dispersed.

The fruit itself is actually food for the seeds which are inside to get a kick start in life!

Because the fruit is a seed pod. It's how the trees reproduce.
