Q:What kinds of inorganic salts are required for plant growth
Only 70 kinds of chemical elements can be detected in plants, but only 16 kinds of essential nutrient elements are needed for the growth and development of internationally recognized higher plants. They are carbon (C), hydrogen (H), oxygen (O), nitrogen (Fe), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo) and chlorine (C1), which can be divided into large nutrient elements, medium nutrient elements and micronutrient elements according to their requirements, such as carbon, hydrogen, oxygen and nitrogen Phosphorus, potassium, copper, zinc, molybdenum and chlorine.Now there are scholars that nickel (Ni) is the first 17 kinds of essential nutrients.
Q:What substances can detect inorganic salts
Looks like, a lot of inorganic salt ah, this, I suggest you clear the concept of inorganic salt under you.
Q:Will a potassium ion from the inorganic salt KBr attach to NH2 at the end of a carbon chain?
The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
Q:Inorganic salt effect
Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.
Q:would heterotrophic organism grow well in inorganic salt media? why or why not?
No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
Q:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
Speaking of calcium, many people will think of white calcium or calcium carbonate powder, and even rich in calcium food, often people mention nothing more than white milk and tofu. In fact, in the high calcium content of food, in addition to shrimp, most of the other looks very black. Every 100 grams of food in the calcium content of more than 300 milligrams of food with kelp, seaweed, Nostoc, black fungus, black sesame and other black food, and some calcium content even up to thousands of milligrams, and milk calcium content is only in the middle level , About 100 grams per 100 grams of calcium. People's Liberation Army 305 Hospital Digestive Medicine chief physician Wang Zhijin said that these black food calcium content is indeed high, but the taste, taste less than some milk, some people, especially young people do not love to eat. And calcium can not just look at the content of calcium, the most important thing is the absorption of the human body, at this point, the advantages of milk is very obvious. The nutritional content of each food is not a single, milk in the same calcium supplement, but also provide a lot of protein, amino acids, fat and vitamins, and kelp is rich in iodine, black fungus has now become an effective prevention of heart Cerebrovascular disease one of the foods.
Q:The lack of three major inorganic salts can cause symptoms in the plant
Potassium: Stable stem to promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry. In addition to these three types of inorganic salts, plants also require many types of inorganic salts.
Q:Is the inorganic salt related to the excitement
Nerve impulses are transmitted in all or no way without attenuation along the nerve fibers. The conduction velocity of the action potential varies depending on the type of the animal, the type of nerve fibers, the thickness and the temperature.
Q:Cells in the water, inorganic salts, protein, lipid
Plus a "so" on the right, because there are many other compounds in the cell
Q:What is inorganic salt
Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salt ions in the body fluid regulate the permeability of the cell membrane, control the water, maintain normal osmotic pressure and acid-base balance, and help transport the general element to the body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiologic functions, which are constituents of enzymes that make up enzymes, hormones, vitamins, proteins and nucleic acids, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
