Do orchids need microorganisms? Why?
Orchids needed a bacteria fertilizer. First of all, the bacteria fertilizer could provide the necessary nutrients for the orchids. The carrier of the beneficial bacteria contained a large number of elements such as nitrogen, phosphorus, and potassium needed for the growth of orchids. Secondly, the beneficial bacteria in the fertilizer could improve the soil environment, such as changing the soil's pellet structure, balancing the soil's ph, etc., so as to create more suitable soil conditions for the growth of orchids. In addition, beneficial microorganisms multiplied in the soil, forming a biological barrier at the roots of orchids to protect them from soil-borne diseases such as stem rot, root rot, and anthracnose. In addition, the bacteria fertilizer could also induce orchids to produce a variety of resistant protein, improve the resistance of orchids to cold and drought, and thus increase the survival rate of orchids, promote the growth of orchids, and also help extend the flowering period of orchids.

Microorganisms or Immunity
Microorganisms were closely related to immunity. Microorganisms play an indispensable role in the development and function of the immune system. Animal genomes alone could not build a mature immune system. The participation of microorganisms was necessary. In the early stages of development, microorganisms can influence the immune system to create a complete immune cell type, and can also help the development of immune organs that store these cells. When the immune system was built and started working, the microorganisms continued to help adjust its response to external threats. From the perspective of inflammation, microorganisms could stimulate immune cells to trigger inflammation and induce anti-inflammatory cells, thus balancing the immune response of the human body and preventing continuous infection due to insufficient inflammation or excessive immune response, which would lead to inflammation and autoimmunity diseases such as asthma and inflammation. For example, the protein A on the surface of Bacteroides frailis could repair the immune system of sterile mice, restore the number of helper T cells, and prevent diseases caused by excessive immune system reactions such as inflammation and multiple stiffen. At the same time, the relationship between microorganisms and immunity was also reflected in the immunity of microorganisms. For example, in the deep sea environment, it was found that bacteria and archaea, two very different microorganisms, were immune to the same virus. This phenomenon indicated that there might be complex interactions between microorganisms that affected immunity, and symbiotic microorganisms might improve their ability to fight viruses through horizontal transfer of immunity. In addition, the inhibition of microorganisms was also related to immunity. The metabolism produced by some microorganisms or by virtue of their own characteristics inhibited the growth of other microorganisms. This process also indirectly affected the interaction between the immune system and microorganisms. For example, in the agricultural field, the use of spores and fungi to prevent soil-borne diseases, and in the food industry, the use of yogurt bacteria and natamin to prevent food spoilage. In the field of medicine, the use of microbial-derived antibiotics and probiotic regulation of the balance of the intestinal flora to suppress the growth of harmful bacteria were all manifestations of the phenomenon of microorganisms in different fields. These were all related to immunity to varying degrees. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are some examples of microorganisms being friends and foes in the story of microorganisms?
As friends, lactobacillus bacteria are used in making yogurt. They ferment the milk and give yogurt its characteristic taste and texture. As foes, bacteria like Staphylococcus aureus can cause skin infections if they get into a cut on our skin.
Orchids in Literature
Orchids were beautiful flowers that often appeared in literature. The following are some literature works related to orchids: In Dream of the Red Chamber, Lin Daiyu liked orchids. She once said to Xue Baochai's orchids," Although the orchids there are not good, they are also expensive." 2 The Tang Dynasty poet Bai Juyi wrote in his poem,"Farewell to the Ancient Grass of the Plain":"The grass on the plain withers and thrives every year. The wildfire never ends, and the spring breeze blows, it grows again. The far-off fragrance encroaches on the ancient road, the clear green connecting the deserted city. And send the prince to the lush garden to bid farewell." Among them, the "far-reaching fragrance invading the ancient path" referred to orchids. 3 In the Ming Dynasty novel Water Margins, Lin Chong once wrote a poem when he was gathering at Liangshan Lake: "Little Li Guang, Hua Rong, alone Mars, four fire, brave stars, deep wisdom, brave stars, righteousness, thin sky." The four flames will flatten the path of tigers and wolves." Among them,"Little Li Guang Hua Rong" referred to orchids. In the modern self-mockery, it was written: " The orchid leaves are luxuriant in spring, and the osmanthus flowers are bright in autumn. This is a happy business. Who knew that the people who lived in the woods would sit and enjoy each other when they heard the wind? Plants have their own hearts, why ask for a beauty to break them?" Among them, the words "orchid leaves in spring" and "osmanthus flowers in autumn" referred to orchids. There were also many other literary works that described orchids, such as " Lancome's fragrance floating in the evening moon " in " Dream of the Red Chamber "," The brave and intelligent star is righteous " in " Water Margins ", and so on.

What are the benefits of friendly microorganisms in the human body according to the friendly microorganisms story?
They are beneficial for the immune system. Friendly microorganisms in the gut can interact with immune cells. For example, they can help train the immune system to distinguish between harmful and harmless substances. They also help in maintaining the balance of the microbial community in the body. If this balance is disrupted, it can lead to various health problems. So, these friendly microorganisms are like little guardians inside us.
What are the characteristics of novel microorganisms?
Novel microorganisms often have unique genetic makeup and metabolic pathways that set them apart from known species.
Why are microorganisms the stars of genetics?
Microorganisms were the " stars " in genetics for the following reasons: microorganisms were small, had a short life cycle, and could reproduce rapidly on simple synthetic media, which allowed a large number of individuals to be processed under the same conditions, providing sufficient sample size for genetic research. In the 1940s and 1950s, the development of microgenetics promoted the clarification of some basic theories in genetics, and in the 1950s and 1960s, it promoted the development of molecular genetics. In addition, the complete sequence of a large number of microorganisms 'genomes had been determined, which allowed people to study the genetic laws and characteristics more specifically at the genetic level, contributing to further revealing the mysteries of life. Moreover, microorganisms had the characteristics of vigorous growth, rapid reproduction, strong adaptability, easy mutation, wide distribution, and many types. These characteristics determined that using microorganisms as research materials had a natural advantage, greatly shortening the research cycle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Observation and identification of the characteristics of microorganisms
The culture characteristics of microorganisms could be observed and identified by their performance on different media. ** I. Tilted Medium ** 1. ** Appearance ** - Microorganisms could take on various forms on the slanted medium, such as silk-like, bristle-like, bead-like, sparsely spread, branch-like, or root-like. These different morphological characteristics were helpful for the preliminary distinction and judgment of the types of microorganisms. 2. ** The significance of observation ** - When observing the culture characteristics of microorganisms, the form presented on the inclined medium was an important reference. For example, if a thread-like growth of microorganisms was observed on the slanted medium, combined with other characteristics (such as color, texture, etc.), it could be distinguished from the microorganisms that grew in a bristle-like manner. Then, it could be inferred as to the type of unknown microorganisms or judged whether the pure culture was contaminated. ** 2. Liquid medium ** 1. ** Appearance ** - In a liquid medium, the growth of microorganisms had many manifestations. It could be turbid, which meant that the microorganisms multiplied in large numbers in the liquid, making the medium turbid and unclear. It could also be flocular, which meant that the microorganisms gathered to form a structure similar to cotton wool. It could also be sticky, which meant that the medium was sticky. It was also possible to form a membrane, which formed a layer of membrane on the surface of the liquid. It was also a common situation that the upper layer of the liquid was clear and the bottom was precipitous. 2. ** The significance of observation ** - By observing the growth characteristics of microorganisms in the liquid medium, one could further understand the characteristics of microorganisms. For example, there may be differences in growth habits and metabolism characteristics between the microorganisms that form the membrane and the microorganisms that make the medium turbid. These characteristics could assist in identifying the types of microorganisms, and were of great significance in studying the growth law of microorganisms and the production of metabolism products. ** 3. Semi-solid medium ** 1. ** Appearance ** - Microorganisms would grow in different ways when they were punctured in a semi-solid medium. It may spread around along the line of inoculants, or it may only grow along the line, or it may grow well in the upper layer, or even connect into a piece, and rarely grow at the bottom, or it may grow well at the bottom, and the upper layer may not even grow. 2. ** The significance of observation ** - This growth characteristic was crucial for determining the dynamic characteristics of microorganisms. If the microorganisms spread around along the line, it usually meant that the microorganisms had strong mobility; if they only grew along the line or were limited to a certain area (such as the upper or lower layer) in the semi-solid medium, it meant that their mobility was weak or non-mobility. This helped to classify and identify microorganisms, especially when it came to distinguishing different types of bacteria with different athletic abilities. During the entire observation and identification process, it was necessary to ensure that the incubation process was not contaminated by other microorganisms. In addition to ensuring that the working environment avoided or reduced the contamination of miscellaneous bacteria as much as possible, it was also very important to master various sterile operation techniques. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
