A. Hybrid varieties are often much larger in size than open-pollenated varities of fruits, vegetables, and grains. Not all food plants can be made into hybrids, but many are. There is no genetic engineering in making hybrid crops, but it involves some very elaborate plant crossing techniques. Again, they make a lot of money selling water-pumped foods. Organic growers need to select plants based on their ability to fit within an organic rotation program, that look good and taste good at the market, and that make them unique from what you get from a chain store.
Fruits are bigger by nuitritional input.
Nitrogen promotes a lot of growth in plants, but plants, like any other organism, can grow big and still be somewhat under-nourished because other basic mineral elements are in short supply. Inputs of fertilizers can result in larger sized cells, and therefore larger sized leaves and fruits. Because of these three factors, you end up with often smaller, tastier fruits, leaves, veggies and seeds in organic production. Also, you get more brillant coloring, variety of coloring and variety of flavors in organic foods. This is absurd, because in so may ways, people are comparing apples and oranges.
