Verschil groente en fruit
Carla Verwijs
Wat was ook al weer (in theorie) het verschil tussen groente en fruit,
heeft iemand daar een beschrijving van? Ik herinner me dat bijv. tomaat
dan fruit is, terwijl de meeste mensen het groente noemen. Maar ja,
waarom is het toch fruit?

Gokje , groenten zijn de plant , Fruit zijn de voortplantingsorganen van
de plant ?

Door je vraag werd ik nieuwsgierig en heb onderstaande opgezocht in de
encarta website, zie onderstaande artikelen.
In addition, fruits such as the tomato and seeds such as the pea are
commonly considered vegetables.
Ofwel fruit is het is het zaad van een plant.

Fruit
I. INTRODUCTION
Fruit, seed-bearing structure of a flowering plant. A fruit is actually a
ripened ovary, a component of the flower's female reproductive structure.
Fertilization of the egg, or female sex cell, within the ovary stimulates
the ovary to ripen, or mature. Depending on the type of plant, the mature
ovary may form a juicy, fleshy fruit, such as a peach, mango, apple, plum,
or blueberry. Or it may develop into a dry fruit, such as an acorn,
chestnut, or almond. Grains of wheat, corn, or rice also are considered dry
fruits. Certain foods commonly termed vegetables, including tomatoes,
squash, peppers, and eggplant, technically are fruits because they develop
from the ovary of a flower.
Fruits are vital to humans. Worldwide, over 430 million tons of fruit are
produced each year, with China and the United States counted among the top
producers. Corn, wheat, rice, and other grains were staple foods in early
civilizations and are still a basic part of the human diet worldwide. Ten
out of the eleven most important food crops in the world today are grains.
Many of these dry fruits serve as the raw materials for important industries
since they are processed into bread, beverages, and alcohol. Grains also are
used as feed for livestock. Today the livelihood of countless farmers is
directly related to the raising of these crops or the raising of the cows,
pigs, sheep, and other animals that feed on them. Over 1.8 million metric
tons of the major grains-corn, wheat, and rice-were produced worldwide in
1998.
Many species of mammals, birds, and insects rely on fruit as an essential
component of their diet. Fruits also play a critical role in dispersing
seeds, increasing the likelihood that at least some will land in an
environment favorable for germination, or sprouting, which helps to
perpetuate the plant species. Birds, for example, help distribute seeds when
they feed on berries. The seed within the berry passes through the bird's
digestive tract and is deposited at a location where, if conditions are
favorable, it will flourish. Most of the 250,000 known species of
seed-producing plants have survived because their fruits serve as the
vehicles that help spread seeds.
Fruits come in a wide range of sizes, shapes, and colors. The tiny floating
plants known as water-meal are only 1 to 2 mm (0.04 to 0.08 in) wide and
have very small flowers. Their miniature ovaries develop into fruits that
are barely visible. Watermelons, on the other hand, may be more than 60 cm
(24 in) long and weigh more than 20 kg (45 lb). Jackfruits, found in the
tropics, can weigh more than 40 kg (90 lb). Diverse fruit shapes abound,
including round grapefruits, oval eggplants, elongated bean pods, and
star-shaped star anise. Pale to intense shades of orange, red, yellow, and
even purple can be found in fleshy fruits, while dry fruits display many
tones of brown.
Vegetable
Vegetable, the edible product of a herbaceous plant-that is, a plant with a
soft stem, as distinguished from the edible nuts and fruits produced by
plants with woody stems such as shrubs and trees.
Vegetables can be grouped according to the edible part of each plant: leaves
(lettuce), stalks (celery), roots (carrot), tubers (potato), bulbs (onion),
and flowers (broccoli). In addition, fruits such as the tomato and seeds
such as the pea are commonly considered vegetables.
Most vegetables are valuable sources of vitamins, minerals, and fiber and
are low in fat and calories. With cereals and legumes, they are important to
a healthy diet (see Nutrition, Human).
