Cultivated plants and wild plants
Wild plants are just that, they have grown in the wild with very little help from humans. It grows on it's own with no human interference.
A Cultivated plant is like a Rose bush, that has been planted by a human, where it gets watered, pruned, weeded, and chemicals are used to keep the bugs away. The owners may use it to create new plants with different colors, or petals with different shapes.
In the evolution of mankind is constantly remade the world to fit their needs. And the breeding of new varieties of plants is one of the ways that exposure. Often the plants obtained as a result of improvement right person of properties, almost nothing like the «original», that is, the plant-ancestor. Let’s consider in more detail what is the difference between cultivated plants from the wild.

Cultivated plants and wild plants
Wild plants are just that, they have grown in the wild with very little help from
humans. It grows on it's own with no human interference.
A Cultivated plant is like a Rose bush, that has been planted by a human, where it
gets watered, pruned, weeded, and chemicals are used to keep the bugs away. The
owners may use it to create new plants with different colors, or petals with
different shapes.
In the evolution of mankind is constantly remade the world to fit their needs. And
the breeding of new varieties of plants is one of the ways that exposure. Often the
plants obtained as a result of improvement right person of properties, almost
nothing like the «original», that is, the plantancestor. Let’s consider in more
detail what is the difference between cultivated plants from the wild.
Where did the cultivated plants
At the dawn of its existence mankind has used what nature gave. The transition
from «savagery» (i.e. appropriating economy – gathering, hunting, fishing) to
«barbarism» – producing economy (cattle breeding, agriculture, craft) of man
faced with the following problem. The yield of cultivated plants was low and could
not meet the needs of people vibrationally life, so it was necessary to increase. As
a result of the selection of the best sample (selection) from «wild» plants were
«cultural», which is a useful organ, the ear, root or fruit is superior (in size,
taste)of their «uncivilized» ancestors.
The main difference between cultivated plants from the wild is that the first can
exist only under the supervision of the person. People, bringing new varieties,
concentrated efforts to make the plant more productive. If wheat, then let the ear
will be noticeably heavier than her «wild» sister, if the fruit – let it be tastier and
bigger than the «wildings».But, getting some quality, plants lose in other. They
become sensitive to external unfavourable influences (bad weather, disease and so
on) or upon termination of care quickly return to their original, wild condition.
Often breeders have a choice to make: high yield, resistance to negative factors or
search for a certain compromise.
How to make wild plants cultural, mankind has explored for thousands of years.
Methods of selection include the following:
selection;
crossing, or hybridization;
polyploidy;
inbreeding.
With the development of genetic engineering has opened up enormous possibilities
for new varieties of plants and new subspecies (and in the future and species) of
animals. The application of genetic engineering techniques will allow you to
create highyielding varieties, resistant to diseases and adverse conditions.
However, genetically modified organisms (GMOs) many believe are harmful to
health. And although it is evidence of their danger is not there, yet GMOs are not
a very long period of time to give a definite answer– they are harmful or not. Now,
it’s not enough statistical material, and it is possible that negative consequences
may occur not immediately, but after two or three generations.
