What is the habit of a green tree, what is a tree with a green trunk?

The trunk of the pure jujube is a green tree.

Trees with green trunks are generally rare. It is generally characterized by strong growth capacity and many lignified cells. Generally, the trunk is relatively thick, and it is suitable for planting in most areas.

There are only two kinds of trees with green trunks, one is the sycamore and the other is the red bean tree. The trunks of these two trees are generally green, and they are also very attractive in shape.

Chinese parasol tree. The Indus River belongs to a tree with a green trunk. It is a deciduous tree.

Its leaves come in many shapes, usually oval or broadly oval, with some short hairs on them. It usually blooms around May. Generally prefer sunny places.

It is currently distributed in China and Japan.

Red bean tree. Red bean trees have a green trunk and can generally grow up to 30 meters tall. Its bark is grayish-green, with a smooth top and dense leaves, the color is generally green, and it is widely distributed on hillsides. At present, it is planted in Fujian, Hubei, Sichuan, Guizhou and other regions.

The shade of green refers to the shaded area where the leaves of the plant are located, and because the sunlight passes through the leaves, a green filtering effect is formed, so the displayed color is also green, which is commonly found in parks, forest areas, residential areas, and other places.

The green shade is a way for plants to adapt to their own light, which ensures that the light of plants can be evenly distributed through the shading effect of leaves, and also plays a certain protective role to reduce the evaporation of leaves due to high temperature water loss. For human beings, the shade of green trees not only provides people with elegant rest, ornamentation and chatting, but also plays a certain role in the alleviation and improvement of the urban environment, such as absorbing exhaust gases, reducing noise and controlling air quality.

Green shade is particularly important in the tropics, where the climatic conditions make it difficult for a larger proportion of crops to grow, and the shade of trees protects crops to a large extent and improves the yield and quality of agricultural products. However, in some urban areas, green shade can become unhealthy due to high ingestion of exhaust emissions and air pollution, especially in winter, when the air quality is poor, and suspended particulate matter can cause tree leaves to lose their green color and wither.

The green shade is a beautiful part of nature, which can not only provide people with a fresh, comfortable and beautiful environment, but also an important means to protect the urban environment and forest ecosystem, we should actively pay attention to the protection of the green environment and ensure the happy life of human beings. <>

Common tree species are: podocarpus, ginkgo, laurel, maple, magnolia, acacia, poplar, poplar, pentagonal maple, Acer truncatum, Acer chinensis, Acer alba spp., Acacia spp., Acacia japonica, Acacia japonica, Robinia pseudoacacia, Salix salix, Salix salix, Betula, Walnut, Eucommia, Tili, Tili, Luan, Torch Tree, Ash, Ash, Ash Ash, Fraxinus Flower, Red Leaf Plum, Elm Leaf Plum, Lilac, Elderberry, etc.

1. Podocarpus.

Podocarpus, also known as podocarpus, long arhat cypress, Jiangnan cypress, is an evergreen tree that can reach up to 18 meters high. Because the podocarpus tree shape is ancient, the combination of seeds and seed stalks is peculiar, after artificial transformation, the podocarpus has a peculiar shape, thousands of manners, vigorous and elegant, graceful and generous, and there are many plantings in temples and houses in the south. It can be planted in front of the door, and the atrium is planted alone, or in the corner of the wall with rockeries and lake stones.

2. Ginkgo. The ginkgo tree is also known as the white fruit tree, and in ancient times, it was also known as the duck's foot tree or the gongsun tree. It is one of the most precious tree species in the world, and Chinese horticulturists often compare ginkgo biloba with peony and orchid, and praise it as the "three treasures of the garden", and respect it as the national tree.

Ginkgo biloba is a tall deciduous tree with a straight trunk, beautiful tree shape, strong disease resistance, high pollution resistance, and a long lifespan, almost thousands of years.

3. Laurel. The laurel tree is an evergreen broad-leaved tree, up to 15 meters high, with a crown that can cover 400 square meters, and a well-developed and deep root system. Gui nationality refers to the tree graceful grace, green branches and green leaves, evergreen in all seasons, is one of the top ten traditional Chinese flowers, set greening, beautification, fragrance in one of the ornamental and practical excellent garden tree species, osmanthus can be clear and dusty, thick energy overflowing, can be called a must.

Fourth, maple trees. Maple, deciduous tree, blooms in spring, mostly granular, yellow-brown and red. The leaves are palmately three-lobed and turn red in autumn.

The maple leaves are palmately 5 shallowly lobed, 13 cm long, slightly wider than long, the 3 largest lobes with a few prominent teeth, the base is heart-shaped, medium green to dark green above, hairy in the axils of the lower veins, and turns yellow to orange or red in autumn. The maple tree in Canada is the most famous.

5. Magnolia. Magnolia flowers, magnolia ornamental trees of the family Magnoliaceae. Also known as white magnolia, spring flower, magnolia flower, magnoliaceae.

It is one of the unique precious garden flowers and trees in our country. Magnolia flowers are native to the Yangtze River Basin, and are now cultivated in Beijing and the south of the Yellow River Basin. Now it is mostly seen in gardens, factories and mines, solitary plants, scattered plants, or street trees on both sides of the road.

Trees are green because they have chloroplasts in plants. Chloroplasts contain chlorophyll, lutein, carotene, anthocyanins and other pigments. The chlorophyll content is overwhelming, masking all other pigments.

The pigment is selective in absorbing the 7 colors of sunlight: red, orange, yellow, green, blue, indigo, and violet. Chloroplasts contain chlorophyll, lutein, carotene, anthocyanins and other pigments. The chlorophyll content is overwhelming, masking all other pigments.

The pigment is selective in absorbing the 7 colors of sunlight: red, orange, yellow, green, blue, indigo, and violet. Chlorophyll absorbs more red and blue light, but does not absorb green light, and reflects it, so the leaves we see in plants appear green.

Leaves are the main organs of plants for photosynthesis and nutrient production. By absorbing carbon dioxide, oxygen is released (release place: stomata), food is provided, and shelter from the wind and rain.

Leaf photosynthesis is done through chloroplasts. If the leaves and cicadas are skillfully combined, the leaves and the song are matched, the "leaf" is homophonic to "night", and the "song" is homophonic to "name", which means that it will be successful in the short term, bringing hope and motivation to people. Similarly, there are also leaves combined with monkeys, bats, etc., among which "monkey" is homophonic to "Hou", which means "marquis overnight"; "Bat" is homophonic to "Fu", which means "a night of happiness".

The cyst-like structure film of chloroplasts in grass is distributed with photosynthetic pigments, which not only absorb blue-orange light and blue-violet light, but also other wavelengths of visible light, and absorb very little green light, so the leaves are green.

Photosynthetic pigments are distributed on the cystic membranes of chloroplasts, and there are many enzymes required for photosynthesis on the cystic membranes and in the matrix.

In the basal granule of chloroplasts, chlorophyll is contained, and the pigments are divided into chlorophyll and carotenoids, and chlorophyll is divided into chlorophyll a and chlorophyll b, which mainly absorb orange light and blue-violet light. Carotenoids are divided into carotene and lutein, which mainly absorb blue-violet light.

Because of the chloroplasts inside the grass, the chlorophyll inside the chloroplast is green. Chlorophyll is a heterocyclic compound centered on magnesium, which has a relatively high absorption rate of visible light except green and a relatively high reflectivity of green light.

The temperature effect of summer will increase the hydration of the dormant buds of the plant, and the hydrolase and oxidoreductase enzymes will enter the active state, which will promote the transformation of organic matter and strengthen the respiration, so that the conditions required for the plant to break the dormant state are exactly the same as the natural conditions in early summer.

This is in the long-term evolution of plants, and what season plants choose to sprout and grow is mainly determined by the amount of DNA (deoxyribonucleic acid) in plant cells. With a large DNA content, the plant germinates early, and vice versa, so the grass is green.

The color of the leaves.

It must be common sense that the leaves are green, so the reason for the greenness is: the chloroplasts in the leaves. Chloroplasts are the food machines of trees, and chloroplasts produce starch (light and reaction) by mixing with water, carbon dioxide and sunlight.

As for chloroplasts being green, at that time, because chloroplasts served plants long before the birth of humans, humans only gave names based on the color of chloroplasts.

When autumn comes, the leaves turn yellow or red because the chloroplasts are destroyed, so that the yellow or red chroming substances such as lutein in the leaves are revealed, and the leaves change color. The reason is that chlorophyll is the most abundant, which shades other pigments, so the leaves are green in summer.

As for the other reasons, there is no in-depth understanding, there should be no other reasons, and it is generally believed that chloroplasts dye the leaves green.

This is because it contains chlorophyll. All green plants rely on chlorophyll for photosynthesis to produce organic nutrients, and chlorophyll absorbs the energy of red, yellow, and blue-violet light when photosynthesizing, and green light does not absorb at all and is almost completely reflected, so in the eyes of people, the parts of plants containing chlorophyll are green.

Chlorophyll is a heterocyclic compound centered on magnesium in trees, which has a relatively high absorption rate of visible light except green, and a relatively high reflectivity of green light.

Because the leaves break down the green components of the sun, they absorb everything but the green light. Scientists have experimented with breaking down the green component of sunlight and shining it on leaves, which quickly die. So, the leaves are green. (This is what my brother said, I don't know if it's right.) ）

Plants need to photosynthesize, photosynthesis requires the participation of chlorophyll, while chlorophyll a and chlorophyll b mainly absorb blue-violet light and red-orange light, and carotene and lutein mainly absorb blue-violet light. Chlorophyll a and chlorophyll b absorb the least amount of green light, which is why the green light is reflected and the chloroplast appears green.

Leaves contain chloroplasts, and chloroplasts contain the most chlorophyll, accounting for about three-quarters, so the leaves appear green.

There is also the fact that the photosynthetic pigments in the chloroplasts of plants basically do not absorb green light, so that green light is transmitted, so we see that the leaves are green.

It has chlorophyll itself, and when the light hits the grass, the grass absorbs other light, and the green light is of no use to it, so it is reflected and enters the human eye, and we see the green grass!

Among the chloroplasts in the leaves, there are four photosynthetic pigments: chlorophyll a, chlorophyll b, carotene and lutein. Visible light is formed by mixing seven colors of light together, these four photosynthetic pigments mainly absorb the light waves of the blue-violet light area and the red light area, but do not absorb the light waves of the green light area, so the green light will be reflected by the leaves, and the light of other colors is absorbed, and we people will see that the color of the leaves is green.

Because green light is most easily absorbed by plants, and the light is reflected to the human eye, it looks green, chloroplasts are green, because chlorophyll in chloroplasts is green!

Chlorophyll is present in the leaves, and its main role is photosynthesis, and chlorophyll has an extremely strong ability to absorb light. If the chlorophyll solution is placed between the light source and the beamsplitter, you can see that some wavelengths of light in the spectrum are absorbed, so that there are black lines or dark bands on the spectrum, which is called absorption spectrum. There are two strongest absorption regions of the chlorophyll absorption spectrum:

One in the red part of the wavelength of 640 660 nm, and the other in the part of the blue-violet light at the wavelength of 430 450 nm. In addition, there are inconspicuous absorption bands in the orange, yellow, and green parts of the spectrum, with the least absorption of green light, especially for green light. Since chlorophyll absorbs the least amount of green light, the solution of chlorophyll appears green.

Trees have green leaves that use chlorophyll to make nutrients through photosynthesis. Roots absorb groundwater and undergo complex chemical changes to produce the necessary nutrients for tree growth. There are chloroplasts in green leaves, it contains chlorophyll, lutein, carotene, etc., and there are red, yellow, blue, green, violet, etc. in sunlight, and the pigment absorbs light selectively, chlorophyll, only absorbs red light and blue light, other light does not absorb, green light does not absorb, which green light shines on the leaves are reflected back, so what we see is green leaves.
