Autumn



What a beautiful color paper the trees when it comes autumn foliage falls out and I took the picture on a trip with my children when they witness the image I did not expect this aspiration a fascinating view


the third season of the year, when crops and fruits are gathered and leaves fall, in the northern hemisphere from September to November and in the southern hemisphere from March to May.
"the countryside is ablaze with color in autumn"

Have you ever asked yourself what the reason for the color change to green color to these securities Alocefro orange or even red,
To find the answer to this question must first understand what is the nature of the leaves of trees and what is its primary function?.

The leaves of trees "food factories in nature", the plants take water from the ground through their roots, and up to the carbon dioxide from the air. The role of sunlight from plants that can be turned on the water and carbon dioxide into glucose (glucose is a type of sugar). The plants use the glucose as a source of food for the supply of energy.
And called on the process of photosynthesis - the process of converting plants to water and carbon dioxide into sugar, and there are a chemical help of a photosynthetic material "chlorophyll", and this article is that gives plants their green color. Once the summer ends and autumn begins, and shorten the day by the day, the trees begin to initialize itself to welcome winter.
As the winter is not available light and water it in large quantities to complete the process of photosynthesis, begins the trees to take a break and live on the food that I made during the summer, and close plants, food and disappears chlorophyll from the leaves and thus their green color until it reaches the color to yellow or orange, in spite of the presence of leaves during the summer, these colors but it can not be observed because it is covered with chlorophyll.
And frequently red and violet among the leaves of trees in the winter, such as "Maple - Maple", because glucose is concentrated in these leaves after photosynthesis stops, and turns both sunlight and cooler nights this fall glucose to the color red.
The brown color of trees like the trees, "Oak - Oak" is composed by the dust and dirt that stick to the surface of the leaves.
This is the group disappears and the reasons behind the mystery of the leaves change colors magnificent that we see in the winter.
