Fig leaves contain amino acids, stigmasterol, citronellol, psoralen and rutin. Root and root bark contain psoralen, bergamot lactone and so on. The fruit contains glucose, fruit acid, sucrose, citric acid and a small amount of fumaric acid, succinic acid, malonic acid, oxalic acid, malic acid and plant growth hormone. The milk of stems, leaves and fruits contains rubber, steroids, protein and starch glucoamylase.
The roots of figs disperse blood stasis, reduce swelling and stop diarrhea. Treat muscle and bone pain, enteritis and diarrhea. Fruits moisten the lungs and relieve cough, clear away heat and promote fluid production, strengthen the spleen and stop diarrhea. Treat cough, asthma, sore throat, carbuncle and hemorrhoids.
Magic leaves
Because the energy on the earth is constantly being consumed, scientists are working hard to study various renewable energy sources and constantly discover new energy sources, among which green leaf power generation is one.
Trees can not only create a green environment for human beings, but also the green leaves of trees have a peculiar function-photoelectric effect, which is discovered by scientists through in-depth research and experiments, that is, green leaves can generate electricity. Scientists use special instruments and high-sensitivity miniature ammeters to measure the photoelectric effect of green leaves under the sunlight at eight or nine o'clock in the morning. The current is 15 microamperes. Although it is extremely weak, it will increase with the increase of light receiving area of green leaves. And after in-depth study, it is found that the photoelectric effect of green leaves occurs at the same time. When the sun shines on the green leaves, the green leaves can absorb light energy and capture electrons from the water, and these captured electrons are constantly moving freely and gradually gathering; The fixed current field can make these electrons move directionally, forming an electron flow, that is, green leaf current. After energy conversion, scientists found that green leaves have great power generation potential. Because there are many chloroplasts in the internal structure of each leaf cell, the total chloroplast area of a tree is equivalent to a giant solar energy conversion station when it is converted into energy. After continuous research, using green leaves to generate electricity to provide new energy is gradually becoming a reality. For example, people can plant trees in a large area, plant wisteria, Parthenocissus tricuspidata and other plants on the wall, and form a multi-layer covered plant group with green leaves, which can not only beautify the living environment, but also build a truly environmentally friendly small power plant, and meet people's demand for electricity through green leaves, which not only saves energy, but also improves the environment. Moreover, scientists have also found that green leaf power generation is not affected by seasons, climate and weather, and can absorb light energy and convert it into electricity at any time. We believe that such a magical and practical power generation method will be more and more loved and welcomed by people.
A small green leaf contains energy beyond human imagination, from which we can predict that there are still many new energy sources on the earth that have not been discovered by human beings waiting for us to explore and study.
Spinach leaves generate electricity.
According to the website of Nature magazine, researchers at the Massachusetts Institute of Technology in the United States have invented a new type of battery that uses plant protein as energy through biotechnology with reference to the manufacturing principle of solar cells. Scientists isolated protein from chloroplasts of spinach leaves and put protein into a special device with two layers of conductive substances to make a battery.
Because protein molecule is very small, it will lose its activity if it leaves the original natural environment, so the process of extracting protein is very complicated. Scientists mix these protein molecules with a peptide molecule, which can form a protective layer outside protein molecules, creating a living environment similar to that in plants. After that, scientists spread the extracted protein molecules on a gold film, and then added a layer of organic conductive material on it to make a sandwich-like device. When the light shines on this "sandwich", photosynthesis will occur in the device, and finally electricity will be generated.
Functions of plants
Around our living environment, plants are really everywhere, from the humble lichen moss in the corner to the towering giant trees, all of which are its ethnic groups, and their adaptability to the environment is stronger than that of human beings. Without plants, even the "spirit of all things" human beings cannot survive, because plants have the following functions:
First, meet the needs of human economy:
Food, medical care, spices, building materials, resin, rubber, paper pulp, fuel, craft supplies, transportation, household items and other daily necessities that are closely related to us are basically from plants.
Second, meet the needs of human leisure and entertainment:
In recent years, people's quality of life has improved. People who are usually troubled by urban air pollution go to the forest recreation area to do "forest bath" on holidays, which is a civilized and modern fashion leisure activity.
Third, the aesthetic value of soothing the soul:
Flowers and plants in the four seasons symbolize the endless life of the earth, which gives people unlimited spiritual enlightenment while pleasing to the eye. Enhance human's understanding of nature: In the role of plants in the ecosystem, people realize that people are only a part of nature, and people should respect and love nature, so as to live in harmony with nature.
Fourth, keep the living environment stable:
The diversity of plant resources can beautify the environment, adjust the climate, reduce noise, prevent wind and fix sand, conserve water, protect homes, provide wildlife habitats, increase species diversity and maintain the balance of ecosystems.
Verb (abbreviation of verb) provides materials for academic research;
Plants not only provide daily necessities, but also enable many disciplines to obtain research materials and teaching materials from the unique functions of special species.
