What is the relationship between plants and people s health 5

Green plant photosynthesis produces oxygen for people to use, otherwise carbon dioxide would not be able to be processed into usable substances. Eating green plants helps the body absorb various nutrients.

Plants are very closely related to us, and our food, clothing, housing and transportation are inseparable from it. 1.Edible; 2.

It can be used as medicine; 3.Can be viewed; 4.Woody plant stems can be used to build houses, make furniture; 5.

It can be used as a means of transportation, such as horse-drawn carriages, etc. 6.It can regulate the climate and purify the air!

Plants are the primary producers, absorbing the nutrients of the earth, the sun, and carbon dioxide from the environment.

Moisturized by rain and dew, photosynthesis is carried out.

Oxygen is produced to make carbohydrates.

It produces a variety of food, nutrients, medicines, and wood. Plants are the oxygen needed for human respiration**. Plants release oxygen during photosynthesis to purify the environment and provide essential conditions for human survival.

The people live on food:

Plants are the foundation of life – food crops.

Some people put rice, wheat, barley, corn, sorghum, soybeans, beans, sugar beets, sugar cane, peanuts, potatoes, potatoes, cassava.

Coconut and banana are listed as the world's 15 important edible plants, and some people regard rice, wheat, barley, sorghum and corn as the five pillars of cereal food crops.

The people live on food, and they cannot survive without them.

Plants are inseparable from human survival and living relationships.

1. Plants are the main food for humans. Humans need a large number of plants to serve as food, including food provided by crops; Cash crop.

edible oils supplied; Fruit trees and fruits provided by economic plants and much more.

2. Plants provide important raw material resources for human life. Cotton and linen plants provide textile raw materials for human wear; Timber provides building materials for human settlements, building houses, building bridges, etc.

3. Plants provide a large amount of feed for livestock and animal products needed by human beings, and the main energy supply of animals lies in plants, and animals will die because of lack of energy without plants.

Fourth, plants form a forest scale and are the purifiers of the air. Sulfur dioxide from the air of forest plant species.

15-50% less than in the open. In the summer of high temperature and humidity, the absorption rate of sulfur dioxide by forest plants will increase with the vigorous physiological activity of forest trees. Relative humidity.

At more than 85%, forest plants absorb sulfur dioxide 5-10 times faster than the relative humidity of 15%. Humans need to breathe oxygen, while plants can absorb carbon dioxide.

Exhale oxygen. The oxygen released by plant photosynthesis is supplied to humans.

5. Forest plants have a regulating effect on climate. The canopy of forest plants is thick.

In summer, it can absorb, scatter and reflect a part of the solar radiation energy to reduce ground warming. Because the roots of the forest trees go deep into the ground, they continuously absorb the water in the deep soil for the transpiration of the trees, so that the forest normally forms fog and increases precipitation. Without plants, soil erosion leads to greater water scarcity and less arable land.

Plants also regulate the global environment.

6. Plants themselves have the function of conserving water, and the decay layer of dead branches and leaves on the surface of plants is increasing, forming a thick humus layer, which has the functions of strong water absorption, delaying runoff and weakening flood peaks. The canopy of the tree has a trapping effect on rainwater, which can reduce the impact of rainwater on the ground.

Conserve soil and water. The canopy can hold back 10-20% of precipitation, most of which evaporates into the atmosphere, and the rest falls to the ground or seeps into the soil along the trunk of trees to become groundwater.

7. Plants in complex ecosystems.

As a producer, it supports the existence of various biological chains. Plants are the main source of energy, an important part of the energy cycle, and the main body to maintain the balance of the ecosystem.

The emergence and development of human beings have always been accompanied by plants; People's perception of plants has undergone a process of constant change. Human beings rely on the minimum living conditions provided by plants, such as perching, feeding, laboring, etc., and plants will quickly be fatal to human survival once they are lacking, and no matter the survival or living environment, they all restrict the safety of human beings.

1. Plant role 1: Plants are the first producers in nature, that is, primary producers. Plants contain chlorophyll, which can convert solar energy into chemical energy through photosynthesis and store energy in various forms.

2. Plant function 2: Plants are important for medicinal materials. There are more than 5,000 species of medicinal plants in China alone, and in some other countries, the commonly used medicinal herbs are mainly 119 compounds extracted from 90 plant species.

3. Plant role 3: Plants also play an irreplaceable role in maintaining the balance of the material cycle on the earth.

4. Plant role 4: Plants provide a place for other organisms on the earth to live and reproduce.

5. Plant role 5: Plants play an extremely important role in regulating temperature and soil and water conservation, as well as purifying the atmosphere and water quality of the biosphere.

First of all, the oxygen necessary for the survival of humans and other animals depends on the supply of plants for photosynthesis, and secondly, plants are by far the most important food and energy**, the vast majority of human food directly (grain, vegetables and fruits) or indirect (meat) comes from plants, and the vast majority of human energy oil, coal, and natural gas also mainly come from ancient plants, many plants can also be directly used in medicine or extract active ingredients from them to make medicines, and the raw materials of paper used in books and newspapers also come from plants, in addition, Wood is used to build our homes, cotton and linen are used to make our clothes, trees and flowers beautify our environment and improve our climate, in short, human life is absolutely inseparable from plants.

This is a collection of plants & life, plants & myths, botanicals & specimens, botanicals & pharmaceutics, and botanicals & museums. If you want to farm with your favorite plants, "Pears are not sweet" will send succulents, plant specimens and postcards from time to time.

1. Thousands of plant species are planted to beautify the environment, provide shade, adjust temperature, reduce wind speed, reduce noise, provide privacy and prevent soil erosion.

2. People will place cut flowers, dried flowers and indoor potted plants indoors, and lawns, shade trees, landscape trees, shrubs, vines, perennial herbs and flower beds and plants will be set up outdoors.

3. The artistic types of living plants include green carvings, bonsai, flower arrangements and tree walls. Ornamental plants can sometimes influence history, such as tulip mania. Plants are the foundation of a multibillion-dollar annual tourism industry, including trips to botanical gardens, historical parks, national principalities, tulip fields, rainforests, and forests with colorful autumn leaves.

1. Plant photosynthesis, absorbing carbon dioxide and releasing oxygen. Oxygen to humans.

2. Plants are critical to the regulation of dry and humidity in the biosphere.

3. Plants themselves are food for many animals (including humans).

4. Plants play a very important role in the ecosystem.

Ask your kindergarten teacher...

Without plants, is there food for animals? Without plants, are there animals? Without plants and animals, humans had to drink air and eat mud to survive...

The children who ask questions are really capable, and they will ask questions online at such a young age. Win one, kiss one...

There are many effects. The most basic thing is to clean the air.

Also, in the summer, plants can regulate the local microclimate. That is, the temperature can be lowered.

There are also a lot of green plants that can regulate fatigue.
