In autumn, every leaf turns into a flower

French Nobel laureate philosopher Albert Camus said that autumn is another form of spring. In spring, flowers bloom, while in autumn, each leaf turns into a flower.
Autumn season has started in America. Autumn is more attractive than spring in most parts of the country.

In the mountain ranges, in their valleys and in the plains, the trees and plants in the forests, gardens and the plains are covered with a curtain of colors. The mesmerizing combination of red, orange, yellow, brown and green colors dazzles the eyes.

This season of colors is very short-lived and usually within two weeks the brightly colored leaves dry up and turn yellow, and then the cold and strong winds of winter blow them off the branches and twigs of the trees.

The US state of Pennsylvania’s Department of Conservation and Resources claims that its Keystone State Park has the longest period of autumn-spring colors in the world.

The park is spread over 1200 hectares and has a lot to offer for nature lovers.
Similarly, the authorities of the Canadian province of Quebec say that their mountain ranges offer the most attractive and largest view of autumn colors in the world.

The mountain range from Montreal to the border of the US state of Maine stretches for about 100 km. Maple trees are abundant here.

Their vibrant red, purple and gold leaves in autumn make for a spectacular sight that millions of people travel to enjoy every year.

Autumn colors are not limited to the US and Canada. In most of the countries of Europe, Russia, China, Japan and many regions of Korea, autumn also shows its colors. These treasure colors are also visible in some mountain ranges of Pakistan.

As soon as the autumn spring starts, many people go out for a long drive and enjoy the beauty of nature.
In regions where the weather is mostly warm, autumn is colorless and dull. The green leaves dry up without changing color and fall from the branches.

Why do leaves change color?

Leaf color change is directly related to temperature. Last year, the weather suddenly turned cold at the end of summer in the US, leaving many areas without the traditional fall colors and sights.

Scientists called it an indicator of climate change. However, this year the weather is gradually cooling down and the autumn colors are showing their brilliance.
Experts say that the green color of the leaves is due to a substance called chlorophyll. Chlorophyll combines water and carbon dioxide in sunlight to produce sugar, which is transported through the branch into the plant.

In other words, the leaf provides food to the plant while the plant draws water from the soil through the root to the leaf to produce sugar.

The leaf takes in carbon dioxide from the air and the chemical process of making sugar releases oxygen which is added to the air. Thus, the plant also helps in keeping the atmosphere clean.

In summer, the days are long and the nights are short, so the leaves have enough time to make food for the plant. When the days start getting shorter and the nights get longer and the temperature also starts falling, on the one hand, the time to make food for the leaves decreases, on the other hand, the part of the leaves that is connected to the branch starts to harden as the temperature decreases. Is.
As a result, the flow of water from the branch to the leaf and the supply of sugar from the leaf to the plant is interrupted and then the process stops completely as the temperature drops further.
When the leaf does not get water, its chlorophyll begins to break down, due to which the color of the leaf begins to change and they begin to appear red, purple, yellow and brown to us. This process continues until the leaf dries up and dries up. Even the strong and cold autumn winds break it from the branch and blow it away.

The plant prepares itself for a long period of sleep, taking the cessation of food supply from the leaves and the drop in temperature as a signal of the arrival of winter. This is why most trees are pruned in winter.
