Explain why unripe fruit is often green and bitter, whereas ripe fruit is usually sweet and colorful.?

Answer 1

It's a matter of the evolutionary purpose that led to fruit producing i.e., flowering, plants. The function that fruit serves is to contain the seeds and propagate the plant.

Fruit that is unripe does not hold mature seeds, fruit that is ripe does. The ripe fruit propagates the plant by being eaten by animals, the seeds being excreted (that's what the hard "shells" are for--to protect the seeds). In order to make the fruit attractive to the seed spreading animals, as it ripens it develops a taste and odor that we , and other animals would describe as pleasant.Since even monochrome vision can distinguish shades of grey, the color serves the same purpose-------it has a different appearance than unripe fruit and signals that this is a yummy tidbit, thus furthering the purpose that the plant produced it for in the first place.

Ain't nature wonderful!!

Answer 2

with the aid of defintion :) unrip fruit is eco-friendly b/c it relatively is the "default" coloration of the plant (like leaves and stems). It features coloration because it ripens to entice animals who consume it and unfold the seeds of their poo.

Answer 3

Self preservation. To stop animals and man eating it too early before it ripens. Must be a chemical process that does it
