Difference between fruits and vegetables

While I was researching the difference between fruits and vegetables, I came across this good answer:

According to scientists fruits are mature ovaries of seed-bearing plants and vegetables are plants cultivated for their roots, leaves and other eatable parts. To simplify things, if an eatable part of plant contains seeds, that plant is considered fruit. Another thing that separates fruits and vegetables is carbohydrate called fructose that gives the fruits their sweet taste that vegetables don't have.
