You wonder how they remove seeds from fruits without any trace, amirite?

They breed them so that they don't contain seeds, usually from a genetic mutant which naturally had no seeds, and then they can 'clone' (I put it in inverted commas cos its technically a type of cloning but not in the way you probably think) other trees from this original tree, so all the seedless trees are descended from the original seedless tree.

Also, some are sterile plants that have been exposed to certain plant hormones which prevent seed growth, but this is tricky because the existance of seeds secrete other hormones to help them grow, so if there are no seeds, then they have to be manually exposed to these (called gibberillins) in order for the fruit to mature properly.

Hope this helps!

There are seeds, they just don't have enough time to grow.

Actually, I don't think most seedless plants are breeded using mutants or artificial selection. I believe a process called vegetative propagation is used. Farmers plants the stems, leaves, or roots of a plant instead of a seed. A plant can still grow from those cells, especially if they lack specificity, because then they can differentiate into the different organs of the plant. It's how vegetables are grown all the time because they don't have seeds. things like potatoes, ginger, and carrots are roots, and they don't come from seeds.

You can take this into account into addition to heatherlouise's explanation. Like she said, I think they do treat plants that are grown through vegetative propagation with plant hormones like giberellins. That's why you tend to see those long seedless green grapes that aren't very wide.
