What are the components of green higher plants, and what are the functions of each part?

It is composed of roots, stems, leaves, flowers, fruits, and seeds.

1. Root. Function: It is responsible for absorbing water in the soil and dissolving the ions in it, and has the function of supporting and storing synthetic organic matter.

2. Stems. Function: Transport action, through the xylem.

The water and minerals absorbed by the roots are transported up to the vegetative organs, and photosynthesis is carried out through the phloem.

The product is transported downward.

3. Leaves. Purpose: Contains chlorophyll in the leaf.

It is the main place for plants to carry out photosynthesis. At the same time, evapotranspiration in plants is achieved through the stomata of the leaves.

4. Flowers. Purpose: Pollination. The bright colors and attractive aromas of the flowers are designed to attract insects. With the help of insects, the pollination process is completed to achieve the purpose of inheritance.

5. Fruits. Purpose: Seed dispersal. The watery fruit is usually brightly colored and can attract animals to eat it, while the seeds are carried far away, and when the seeds are excreted, they take root and germinate. Some fruits are very light in weight and are carried by the wind when the wind blows.

Go to faraway places and complete their mission of passing on their lineage.

6. Seeds. Role: Seeds play an important role in the continuation of species.

Seeds are closely related to human life, in addition to the daily necessities of grain, oil, cotton, some medicinal (such as almonds), flavoring (such as pepper), beverages (such as coffee, cocoa) all come from seeds. Plants, trees, flowers and plants are also propagated from seeds. Many of the seeds are edible and are a delicacy on the table.

Green flowering plants are composed of six parts: roots, stems, leaves, flowers, fruits, and seeds. The roots stretch out in the soil and absorb water and inorganic salts from the soil, providing inorganic nutrients to the plants.

Summary. Green plants can convert the absorbed water and carbon dioxide into primary products --- carbohydrates through photosynthesis, and further synthesize them into fats and proteins, which can be used to build themselves, so that solar energy can continue to enter the ecosystem through the synthesis and transformation of producers, becoming the only thing and energy for other biological groups**.

Environmental ecologists tell us that the lush flowers and trees in the spring forest produce a large number of negative ions during the metabolism. It has been determined that the grassland in the forest contains more than 30,000 negative ions per cubic centimeter of air in spring, compared with more than 50 in the average home.

When people are in a quiet environment with a high concentration of negative ions, their pulse can be reduced by 5 to 10 beats per minute. More importantly, negative ions can directly act on the central nervous system to increase the level of enkephalin, so that people feel comfortable and energetic, and can make the body's righteous qi rise, evil qi greatly decreased, and resist the invasion of various infectious diseases.

Due to the development of urban transportation and industry, people have to burn a large number of various minerals, producing a large amount of carbon monoxide, sulfur dioxide, lead vapor, mercury vapor, ethylene and nitrogen oxides and other toxic gases, seriously affecting people's health. Because green plant leaves have many stomata, they can absorb a large number of these toxic gases.

What role does green plants have, therefore, what and what we want to promote.

Green plants can convert the absorbed water and carbon dioxide into primary products --- carbohydrates through photosynthesis, and further synthesize them into fats and proteins, etc., which are used to build themselves, so that solar energy will continue to enter the ecosystem through the synthesis and transformation of producers, and become the only thing and energy for other biological groups**Environmental ecologists tell us: The lush flowers and trees in the spring forest will produce a large number of negative ions during the metabolism process. According to measurements, the grassland in the forest contains more than 30,000 negative ions per cubic centimeter of air in spring, while there are only more than 50 in the average home.

When people are in a quiet environment with a high concentration of negative ions, their pulse can be reduced by 5 to 10 beats per minute. More importantly, negative ions can directly act on the central nervous system to increase the level of enkephalin, so that people feel comfortable and energetic, and can make the body's righteous qi rise, evil qi greatly decreased, and resist the invasion of various infectious diseases. Due to the lack of urban transportation and industrial development, people have to burn a large number of various minerals, producing a large amount of carbon monoxide, sulfur dioxide, lead vapor, mercury vapor, ethylene and nitrogen oxides and other toxic gases, seriously affecting people's health.

Because green plant leaves have many stomata, they can absorb a large number of these toxic gases.

So we want to have more trees, more green plants, to protect the environment.

The stems of plants also have sieve tubes and ducts that transport nutrients to the plant body.

It should be a flower stalk, a receptacle, 4 sepals, 4 petals, and the stamens are usually 6, 4 long and 2 short, called the four strong stamens and one pistil.

In terms of greening: green and other ornamental plants can be used for greening, rendering a fresh and comfortable environment, and as street trees to absorb dust.

Environmentally: other plants such as green can absorb CO2 and release O2 from the environment under suitable photosynthetic conditions such as sunlight, temperature, and CO2 (at night, due to lack of sunlight, they will also respire and release CO2); At the same time, the green plants around the hospital and the factory usually have the functions of purifying the environment, resisting and disinfecting, and absorbing toxic gases, and some green plants can reduce radiation (cactus family) and purify formaldehyde (tiger tail orchid, monstera, ivy, iron fern, weeping ficus) and so on.

In terms of health care: there is now a kind of "gardening" and refers to an effective method for people who need to improve their physical and mental aspects through the environment and horticultural operations in the garden, and most of the horticultural plants are green ornamental plants.

Of course, there are many, many more roles of green plants...

Of course, the greening of the environment is the most important thing, but I think the most important thing is the photosynthesis that is the producer of the ecosystem, which uses photosynthesis to convert inorganic matter into organic matter, light energy into chemical energy, and it also releases oxygen, which feeds a lot of organisms.

Absorbs carbon dioxide to produce oxygen and organic matter.

1. Synthetic organic matter.

The net annual production of all plants on the planet is about 150 billion to 200 billion tons of organic matter, which is the basic material on which humans and heterotrophs around the world depend.

2. Oxygen production function.

It has been determined that 750 kg and 600 kg of oxygen are released per day per hectare of forest and park green space respectively in summer.

More than 100 billion tonnes of oxygen are released annually by the world's green plants.

3. Wind prevention and sand fixation.

Shelterbelts can be built in wind-damaged areas, and the wind speed can be reduced by about 30% within the protection range; Farmland with shelterbelts has about 20% more yield than those without.

4. Regulate the climate.

According to the measurement, the ground temperature in the green space in summer is generally 10-17 degrees lower than that of the white ground in the square, and 12-22 degrees lower than the asphalt road; In winter, the average surface temperature of the lawn is 3-4 degrees higher.

According to statistics, the average rainfall in woodlands is 16-17% higher than that in non-forested land, and the lowest is 3-4% more.

5. Maintain soil and water.

Scientists have observed that soil erosion is reduced by 60% in 30% forest land compared with non-forest land. Observations of mountainous land with a slope of 13 degrees have also revealed that the amount of soil and sand lost each year is 48 times that of bare land and that of forest land.

6. Absorb poison gas.

More than 300 species of plants have been found to secrete volatile fungicidal compounds, such as fresh peach leaves to repel bed bugs; The smell of cucumbers can make cockroaches flee; Onion and tomato plants repel flies; Woody nightshade or basil repellent mosquitoes.
