This helps the plants get their seeds to somewhere new where they can grow into a new plant.
Why do fruits become soft?
Softer, sweeter and nicer to smell. At the same time as fruit change colour, they also become soft. This is because fruit are made from many tiny things called cells. In plants, each cell has a wall.

Some can ripen on the plant and after picking.
How to accelerate ripening of fruit?
This tip works for climacteric fruits (that give off ethylene gas which in turn speeds up ripening). To accelerate ripening, place any of these fruits in a paper or cotton bag (not plastic because it must be breathable).

Ethylene gas which helps convert starch into sugar both on the plant and after picking. Avocado matures on tree, but only ripens after picking. Tomato – See How to Ripen Tomatoes After Picking. Cantaloupe will soften but not sweeten after picking.
Why do pineapples soften after picking?
In some instances, these fruits may soften after picking as they begin to breakdown (rot, really), but flavor won’t improve. Pineapple may soften after picking but does not become sweeter.
