What is chlorophyll?

What is the main characteristic of plants that distinguishes them from animals? Plants are green. Of course, there are exceptions, but the main requirement for plants is that they must be green.

The green color of plants is one of the basic requirements. The green substance of plants - chlorophyll - absorbs the necessary substances from the soil and air and produces the products necessary for their existence. If plants did not have this property, man and animals would not be able to exist due to the lack of food! Even those beings that eat animal food are dependent on the presence of other beings that eat plant foods. Indeed, plant foods are the beginning of all life on Earth!

Now it is clear to you that chlorophyll, this amazing green substance that provides humans and animals with plant food, is very important for our life! Chlorophyll is found in leaf cells, as well as in stems and flowers.

With the help of chlorophyll, the plant absorbs sunlight and uses the energy received to convert inorganic elements into organic, or "life-giving" chemical elements. This process is called "photosynthesis". Translated from Greek, this word means "light" and "connection".

There are some plants that do not have a green color, that is, they do not have chlorophyll. How do they exist? Mushrooms and the plant family that lack chlorophyll do not produce their own food. So they must get it from somewhere else. If a plant gets its food from other plants or animals, they are called "parasites". If they get their food from the decay products of plants and animals, we refer to them as "saprophytes".

Chlorophyll can be extracted from plants and used by humans for various purposes. In some cases, it kills certain bacteria.

Random interesting fact from the Great Encyclopedia:

Why is the Leaning Tower of Pisa falling?

If the tower in the city of Pisa didn't even "fall", it would still be an absolute miracle. It is built entirely of white marble. The walls at the base are four meters thick. The tower has 8 floors, it reaches a height of 54,5 meters, which is equal to the height of a 15-story building. A staircase built into the wall, consisting of 300 steps, leads to the top. By the way, those who climb this staircase to the very top observe an amazing panorama of the city and the sea.

The upper part of the tower deviated from the vertical by 5 meters. In other words, she "bent over." If you stand on top of the tower and throw a stone, it will fall 5 meters from the base of the tower. Why is she falling? Nobody knows the exact answer to this question. Of course, when it was built, they did not want it to "fall" at all.

She was supposed to stand up straight. It was supposed to become the bell tower of the cathedral, which was located nearby. It began to be built in 1174, and construction was completed in 1350. The foundation of the tower is on the sand. Perhaps this is what caused the "fall" of the tower. But she didn't start falling right away. It started when three floors, or three galleries, had already been built. The project was slightly changed, and the building was "straightened". But it did not help. Over the past 100 years, the tower has deviated by 0,3 meters. Engineers believe that the tower is correctly called "falling" because they are sure that it will fall anyway.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Apple and Google have completely switched to renewable energy sources 11.04.2018

Apple announced that it has completely switched to renewable energy sources.

Now absolutely all of its offices, stores and headquarters, including the newest Apple Park, are powered by renewable energy. In total, Apple currently has 25 such stations that can generate 626 MW of clean energy. Of these, 286 MW are provided by solar power plants, which were opened only in 2017.

Apple adds that 15 new solar power plants are currently under construction. After their launch, the total capacity of such "green" stations located in 11 countries of the world will be 1,4 GW.

Apple's data centers switched to renewable energy, including wind farms, back in 2014. 23 companies from the list of suppliers of components and assemblers of Apple products supported the Cupertino initiative and also began the transition to green energy. The list includes Pegatron, Quanta Computer, Quandrant, Finisar, Ecco Leather and more.

A week ago, Google made a similar announcement.
