In many sometimes we admired a beautiful tree of Willow.

The Willow is a tree from growing very fast, with deciduous leaves, typical of the northern hemisphere and a lover of moist soil. One of the best known members of the family of the Willows is the Weeping Willow, a beautiful plant with typical drooping branches, with elongated leaves that often have a silky or white underside.

The popularity of this tree is largely due to its versatility: the bark is used in medicine for the content of salicin (from which the acetylsalicylic acid, which is the active ingredient of aspirin) anti-inflammatory and analgesic. The wood is used for the construction of furniture, utensils and veneers, the fiber used to produce paper and ropes, the branches are twisted to build baskets, pots and various objects (Wicker).

The leaves are green and absorb sunlight through photosynthesis: we all know this. But as using light and why are they just green? And what they do when it's dark?

The lifeblood of plants is water, the body responsible for the stability of vegetable (thirsty plants become limp), responsible for the transport of nutrients and dilutes the salts.
Through evaporation from the surface of the leaves the water present in the medium is sucked from the roots, in a continuous flow beneficial.

Real fuel photosynthesis, water is dispersed in the light of the basic elements: hydrogen and oxygen. Read more ...

Following the last part of the overview of plant hormones and their functions.

Acid giasmonico

It is a ubiquitous element in the plant, which affects the development and growth but also on natural defense against fungus.

Oligo-saccharides

A group of substances discovered only ten years ago in the Complex Carbohydrate Research Center on Georgia's, whose name means little sugar.
It is in fact carbohydrates formed from 2-8 monosaccharides, products from elements derived from the decomposition of the cell walls (composed of polysaccharides such as cellulose and pectin) and combined with each other.
The oligo-saccharides for the plant have the same importance in humans has insulin. Read more ...

Plant hormones and those humans have some characteristics in common, but those plants are not produced by glands and are transported directly through the cell walls.

In the previous installment of our guide we spoke of auxin, a hormone better known, synthesized for the production of powders for rooting cuttings. Now we see the other types of hormones, no less important for the functions of the plant: Read more ...

The hormones of humans and animals are unique substances that cause reactions in older small quantities and which are produced from special glands but have no effect elsewhere in the body.
A prime example are the male and female sex hormones, called estrogen and androgen, or thyroid hormones: These substances not only affect our physical reactions, but also our social behavior and our thoughts.

Even plants have hormones, as we all found out by reading the product labels for rooting cuttings.
