1. Botany is a science that studies plant life activities, involving plant morphology, structure, classification, physiology, ecology and many other aspects. For us ordinary people, botany may be a distant and profound subject, but in fact, it is around us. As long as we explore it with our heart, we can find its beauty.
Recently, I took an online course in botany. Through this course, I not only learned the basic knowledge of botany, but also learned how to observe and identify the plants around me. This course made me realize that botany is not only a science, but also a way of life and a pursuit of the beauty of nature.
In the course, the teacher led us to know the common plants around us, such as green bristlegrass, neem, wild chrysanthemum and so on. We learned how to observe the morphological characteristics of plants, how to distinguish different plant species, and how to understand the growth habits and ecological values of plants. Through these studies, I found that the world around me has become more colorful and interesting.
For example, when studying dog tail grass, we learned that dog tail grass is a common weed, and its flower spikes are as hairy as dog tail and very cute. At the same time, dog tail grass is also a good Chinese herbal medicine, which can be used to treat carbuncle, tinea and sores and other diseases.
When studying neem, we learned that neem is a common street tree. Its flowers are beautiful, but its leaves and fruits are poisonous to some extent. When studying wild chrysanthemum, we learned that wild chrysanthemum is a common wild flower, and its flowers can be used for making tea, cooking porridge and so on, which has certain medicinal value.
Through the study of this botany online course, I not only learned about the common plants around me, but also learned how to observe and identify them. More importantly, I learned how to appreciate the beauty of plants and how to feel the charm of natural beauty. I believe that as long as we explore and discover the botanical knowledge around us, we can make our life better.
2. Medicinal plants refer to those plants that have medicinal value and can be used to treat diseases and relieve symptoms. In our life, medicinal plants can be seen everywhere. As long as you pay attention to observation and be good at discovering, you can find their traces. Recently, I attended an online course of medicinal botany. Through the study of this course, I have a deeper understanding and understanding of medicinal plants.
In this course, the teacher introduced us to many common medicinal plants, such as licorice, honeysuckle and ginseng. We studied the growth habits, morphological characteristics and medicinal value of these plants. Through these studies, I found that medicinal plants not only have medicinal value, but also have many interesting stories and legends.
For example, licorice is a common Chinese herbal medicine, which has the functions of clearing away heat and toxic materials, resolving phlegm and relieving cough. In ancient times, people thought that Glycyrrhiza uralensis Fisch had the properties of reconciliation and relief, so it was called the king of medicine. Honeysuckle is also a common Chinese herbal medicine, and its flowers can be used to make tea, porridge, etc., which has the effect of clearing away heat and detoxifying. It is said that the name of honeysuckle comes from the color of its flowers. Its flowers are white at first, and then turn yellow, so it is called honeysuckle.
Ginseng is a very precious Chinese herbal medicine, which has the functions of invigorating qi, resolving stagnation and promoting fluid production. In ancient times, ginseng was considered as one of the drugs with mysterious effects, which could only be enjoyed by the nobility and the rich. With the development of science and technology, ginseng can be planted artificially, and the price is gradually close to the people.
Through the online course of Medicinal Botany, I not only learned about the types and characteristics of common medicinal plants around me, but also learned how to use them correctly to treat diseases and relieve symptoms.
Plants are one of the most basic life forms on the earth, and they are closely related to our lives. But what do we know about plants? Recently, I took an online course in botany. Through the study of this course, I deeply understand the mystery of plants and feel the magic of plant life.
In this course, the teacher introduced us to the basic knowledge of the origin, classification and growth process of plants. We also learned how to identify different plant species by observing plant morphological characteristics, growth environment and other factors. Through these studies, I found that the plant world is full of endless mysteries and surprises.
For example, the teacher told us that the leaves of plants are important organs of photosynthesis. Photosynthesis is a process in which plants synthesize organic matter by absorbing solar energy, carbon dioxide and water. This process needs sunlight, water and carbon dioxide, so plants need enough sunlight, water and carbon dioxide to flourish.
The roots of plants are important organs for absorbing water and nutrients. Root system absorbs water through cell infiltration and nutrients through cell active absorption. The roots of plants also need to compete for water and nutrients in the soil to maintain their own growth and survival.
In addition, this course also introduces some special physiological phenomena of plants, such as insect-eating plants and * * * plants. Insectivorous plants refer to plants that can prey on insects or other small animals. They usually have special insect catching organs or trap structures. * * * plants refer to plants that have established a * * * relationship with some microorganisms or insects, which are interdependent and mutually beneficial.
Through the study of this network botany course, I not only learned the basic knowledge and growth process of plants, but also learned how to observe and identify different plant species. More importantly, I learned how to appreciate the beauty of plants and how to feel the magic and charm of plant life. I believe that as long as we explore and discover the botanical knowledge around us, we can make our life better.
With the development of human beings and the progress of science and technology, our environment is also facing more and more pressures and challenges. Environmental protection has become a global problem, and environmental protection plants are one of the important means to solve environmental problems. Recently, I attended an online botany course for environmental protection plants. Through the study of this course, I have a deeper understanding and understanding of environmental protection plants.
In this course, the teacher introduced us to the concept and significance of environmental plants, as well as the role and application of environmental plants in environmental protection. We learned how to identify environmentally friendly plants and how to improve the environmental quality by planting environmentally friendly plants. Through these studies, I found that environmental protection plants not only have ecological value, but also have many other functions and meanings.
For example, some environmentally friendly plants can absorb harmful substances in the air, such as formaldehyde and benzene, and purify the air quality. Some environmental protection plants can reduce noise, prevent wind and fix sand, keep water and soil, and improve urban environment and ecological balance. In addition, some environmentally friendly plants can also be used as biomass energy sources, such as algae and bagasse, to provide renewable energy for human beings.
In this course, I also learned some interesting knowledge about environmental protection plants. For example, the teacher told us that some plants can cope with environmental pollution by regulating their own physiological and biochemical metabolic pathways, such as inducing the synthesis of resistant metabolites. This provides some new ideas and methods for solving environmental problems. In addition, this course also introduces some environmental protection plants with special functions, such as Pteris vittata, which can absorb heavy metals, and tobacco, which can detect pollutants.
Through this online course of environmental protection botany, I not only learned the concept and significance of environmental protection plants, but also learned how to identify environmental protection plants and how to improve environmental quality through planting. More importantly, I learned how to appreciate the beauty of environmental plants and how to feel the role and value of environmental plants in environmental protection.
Botany not only studies plants themselves, but also is closely related to human life, especially in the field of health. Recently, I attended an online botany course about plants and our health, which gave me a new understanding of the role of plants in human health.
The teacher introduced us to the nutritional value of plant food. It turns out that the vegetables, fruits and grains we eat every day provide us with rich vitamins, minerals and dietary fiber. For example, dark green vegetables such as spinach and kale are rich in folic acid and iron, which helps to prevent anemia; Orange and red fruits and vegetables such as carrots and tomatoes contain a lot of beta carotene and vitamin C, which helps to maintain the health of skin and mucous membranes.
This course discusses the application of herbs and plant extracts in medicine. Many modern medicines come from plants, such as paclitaxel (from China yew, used to treat some cancers) and aspirin (from willow bark, used to relieve inflammation and pain). Some traditional herbs, such as ginseng and astragalus, are also widely used in Chinese medicine to regulate the body and treat diseases.
The teacher also mentioned the benefits of plants to mental health. Many studies have confirmed that contact with nature and planting flowers and plants can reduce stress, anxiety and depression. The fragrance of some plants has also been proved to have soothing and relaxing effects, such as lavender and orange blossom. The role of plants in environmental protection and health was discussed. Indoor plants can absorb indoor harmful substances, such as formaldehyde and benzene, so as to purify indoor air. Outdoor green plants can absorb carbon dioxide in the atmosphere, release oxygen and provide a more livable environment for human beings.
