Based on context alone Plants belonged to eukaryota, and prokaryota and plants were different types of organisms. The organic matter in prokaryota included, but was not limited to, the following categories: 1. ** Carborescent **: Prokaryota can synthesize and store sugar substances, such as glycans such as glycogen in bacteria. They are a form of energy storage and are formed by the condensation of multiple glucose molecules. 2. ** protein **: It is made up of an acidic protein. The protein in prokaryota has many functions, such as being used to catalyze biochemical reactions, forming cell structures, etc. 3. Nucleic acid: includes DNA (DNA) and DNA (Ribone-Nucleic acid), which are carriers and communicators of genetic information. They are essential for the inheritance, mutation, growth and development of prokarytes. 4. Lipids: For example, the Phospholiptides in the cell membrane. Phospholiptides form the basic skeleton of the prokaryte cell membrane. They have a waterproof head and a waterproof tail, ensuring the selective exchange of substances inside and outside the cell.

The organic matter that reacted with the Bromine water mainly had the following categories: 1. Unsaturated compounds, such as alkynes and alkynes, would undergo an addition reaction. 2. Aldes, because the formyl group is easily oxided by the Bromine water. 3. It can undergo a substitution reaction with the water of the solute to form tribrom-phenol. 4. The organic matter containing carbon-carbon double bond and carbon-carbon triple bond can make the bromine-water reaction fade; the derivative of the aromatic compound containing the ortho-and para-hydrogen atoms of the aromatic ring and the ortho-and para-hydrogen atoms of the aromatic ring can undergo a substitution reaction on the aromatic ring; the derivative of the aromatic compound containing the carbolic group can undergo an oxidization reaction. 5. 1,2-Dichlorothane's elimination reaction produced an organic compound that could cause the color of the water to fade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following are some exercises for the detection of organic substances in biological tissues: ** 1. Multiple choice questions ** 1. The changes of some organic matter during the ripening process of the rape seeds are shown in the figure. The seeds at different maturity stages were tested after being blended. The correct result is () - [Option A: Take a sample on the tenth day and test it with Fehling's reagent.] Because there was still a lot of dissolved sugar on the 10th day, the reducing sugar in the dissolved sugar and Fehling's reagent would appear brick-red precipitations under the water bath heating condition, so item A was wrong (the answer saying that it did not show color was wrong). - Option B: Test with biuret reagent on the 20th day. The protein was the embodiment of the life activities of the organism. The existence of the protein could be detected throughout the ripening process of the seed, so the B question was wrong. - Option C: Test with the Sultan III reagent on the 30th day. On the 30th day, the fat content was higher, and the fat reacted with the Sultan III reagent to produce an orange color, indicating that item C was correct. - [Option D: Test with an iodinated solution on the 40th day.] On the 40th day, the starch had been exhausted, and there would be no color reaction when tested with the iodoids. Item D was correct. 2. Regarding the identification of reducing sugar in biological tissues, the following statements are correct () - Option A: When measuring 2 mL of Fehling's reagent, a 5 mL measuring cylinder should be used instead of a 10 mL measuring cylinder. This is because a measuring cylinder with an appropriate capacity should be used when measuring the reagent. A is correct. - Option B: When heating with water, the liquid level in the test tube should be lower than the water level in the beaker. This way, the reaction solution can be heated evenly. - Option C: Fehling's reagent is a suspension of CuSO4 solution and a solution of NaOx. The CuSO4 solution is blue in color. Therefore, after adding Fehling's reagent to the tissue sample, the liquid in the test tube will appear blue. After heating it up, it will turn brick-red. - [Option D: Copper (OH)2 is easy to decompose, so Fehling reagent must be prepared and used immediately. It cannot be stored for a long time. D is wrong.] ** 2. Short Answer Questions ** 1. In the concept map of green plants 'photosynthesis and respiration, it might involve knowledge related to the detection of organic matter. For example, photosynthesis produces organic matter (such as starch), and the presence of starch can be detected with an iodine-based solution. If one were to investigate whether different parts of the plant (such as the shade and non-shade parts of the leaves) were producing starch through photosynthesis, they could determine it by detecting the color change of the leaves with an iodine-based solution. 2. In the experiment to verify that green leaves produce organic matter under light: - Step 1: The purpose of placing the plant in the dark for a day and night was to remove or exhaust the original starch in the leaves so as not to interfere with the experimental results. If he wanted to detect the starch in the leaves, this step was a necessary prerequisite. - The purpose of covering the upper and lower sides of the leaves with black paper in step 2 was to set up a set of control experiments. The light-shielded part and the unlight-shielded part formed a contrast to explore the effect of light on photosynthesis (starch synthesis). After that, he could use the solution of iodination to detect the formation of starch in the leaves that were shielded from light and those that were not. - In step 4, the leaves were heated in alcohol with water separating them, so that the leaves dissolved in the alcohol. The leaves turned yellow-white, and the liquid in the beaker containing the leaves gradually turned green. After the leaves were decolored, the starch was detected with an iodine-based solution to facilitate the observation of the experimental results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The removal of organic substances by microorganisms is mainly based on the following principles: 1. ** Catabolization ** - Microorganisms use organic matter as a source of nutrients, and in the process of metabolism, complex organic substances are broken down into simpler compounds through specific digestive systems. For example, microorganisms could gradually degrade the alkyls in oil through biochemical fermentation stages such as alcohol, aldo, keton, fatty acid, etc., and finally degrade them into carbon dioxide and water. - Under the condition of oxygen, the microorganisms would have a more thorough reaction to the organic matter. For example, autotrophs could gradually vaporize nitrogen (NH- N) into nitrogen dioxide (NO2- N) and then re-vaporize it into nitrate-N. In the biological treatment, microorganisms also processed organic matter based on the metabolism of oxygen. - Microorganisms could also carry out metabolism under the conditions of no oxygen or lack of oxygen. For example, under anoxic-deficient or anoxic-deficient conditions, the detoxifying bacteria used organic matter as an electron donor to reduce nitrate-nitrogen and nephetite-nitrogen into nitrogen (N <2>) to achieve the removal of nitrogen. Some microorganisms could not completely decompose the metabolism of the acid into carbon dioxide and water under the anoxic-deficient conditions, but instead, they could decompose it into various acids, alcohol, ketons, etc. 2. ** Biochemical Water Reaction ** - The organic matter would react with water under the action of the hydrolytic acid. For example, under the action of the hydrolytic acid, the glycan is gradually digested into disose, monose, and methyruvic acid; the protein is first broken on the bond, deamin, decarboxylated, and gradually oxified, and the organic nitrogen is converted into the organic nitrogen; many kinds of amine and mineral acid ester pesticide such as parathion, malathion, etc., under the action of microorganisms, the amine and ester bonds in their molecules are also easily digested. 3. ** Biochemical Oxidation Reaction ** - It was an organic matter that was subjected to the action of microorganisms. In the aquatic environment, organic matter was degraded by biological oxygen. Part of it was assimilated by organisms to provide carbon source and energy for organisms, and then converted into biological metabolism substances. The other part was decomposed by the catalyst produced by biological activities. The biochemical oxygen of organic matter is mostly the dehydration of oxygen. During the dehydration of oxygen, it can be dehydrated from the-CHOx or-CH ^- CH ^-group, and the removed hydrogen is transferred to the hydrogen receptor. If the oxygen molecules are used as the hydrogen receptor, it is an oxygen oxygen decomposition process. If the combined oxygen (such as CO, SO, NO, etc.) is used as the hydrogen receptor, it is an oxygen free decomposition process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Additional reaction: - The addition reaction of ethene and Bromine: <<CH2 = CH2 + Br2> - The addition reaction of ethene and hydrogen bromidate was as follows: <CH2 = CH2> - Under certain conditions, addition reactions could also occur between ethene, hydrogen, and water. Since the chemical properties of ethyne (carbon-carbon triple bond) were similar to that of alkene (carbon-carbon double bond), similar addition reactions could also occur. - The aromatic ring can undergo an addition reaction with hydrogen (in the presence of a catalyst such as Ni). - Aldol groups can undergo a reduction reaction (addition reaction), such as: <anno data-annotation-id ="00000000 - 4c00 - 4c00 - 8c00 - 9c00 - 9c000b000000"> CH3CH20H </anno>. Substitution reaction: - The substitution reaction between methane and Cl2: CH4 + Cl2. - The substitution reaction of the aromatic ring: For example, the substitution reaction with the aromatic group using FeBr3 as a catalyst; the nitration reaction with the aromatic group using concentrated sulfuric acid under heating conditions (the hydrogen on the aromatic ring is replaced by the nitrogen group). - The substitution reaction of the halated carbon was as follows: <<CH3CH2Br2>+<NaBr2>>. - The substitution reaction of alcohol: <CH3CH20H>+<br>> longrightarrow <CH3CH2br>+<H2O>> - The ester's cleavage reaction (which can be seen as a substitution reaction):<CH3COOCH2CH3 + H2O> <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The amine group was basic and could react with an acid to form a salt. For example, it could react with a sulfuric acid to form an amine salt. When heated, the amine salt would lose water and become an amine. An organic compound containing an amine group can also undergo an animation reaction, such as the animation of a Halide.(Often used as an agglomerating agent, the reaction is carried out at high temperature and high pressure. Copper salt is used as a catalyst for the inactive halo on the aromatic ring, and the halo on the fatty chain and the halo activated by the ortho-or para-nitro group on the aromatic ring do not need a catalyst), and the alcoholization of alcohol or ol (volatile alcohol or ol can be agglomerated with hydrogen in the presence of a catalyst in the gas phase under high temperature and high pressure. The alcohol or ol that is difficult to be agglomerated can be agglomerated with hydrogen in the liquid phase under high temperature and high pressure). In addition, the reduction of the nitrogen compound could produce an organic compound containing an amine group, which could also be seen as a reaction related to the amine group. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Procaryotes had the following characteristics: 1. ** Group Form ** - ** On the solid medium **: You can observe its size, shape, bulge, edge, color, and clarity. Its colony characteristics were usually moist, viscous, smooth, transparent, easy to pick, uniform texture, consistent color of all parts of the colony, and small colonies. However, the colony's characteristics would be affected by factors such as the neighboring colonies, the cell structure and growth behavior of the colonies, the cultivation conditions, and the cultivation time. - ** Semi-solid medium **: In the semi-solid medium, it can be used to judge the respiratory type and movement ability of cells; in the semi-solid medium of gelatins, it can be used to judge whether the bacteria produce a protein. - [On the liquid medium: Different colony forms.] 2. ** Individual form of cells ** - ** cocci **: It is spherical (single) or nearly spherical (a little flat when several are connected together). - ** Bacteroides **: There are single rod, double rod, chain, fence, and eight shapes. - ** Spirillum related **: Vibrios have less than one spiral; Spirillum has 2 - 6 spiral rings, and the bacteria is hard; Spirillum has more than 6 spiral rings, and the bacteria is soft. In addition, when the bacteria were young or under suitable growth conditions, they would be in a normal and neat form. When they were older or under abnormal conditions, the cells might be deformed or degenerate. 3. ** size expression **: Spheroidal bacteria are expressed in diameter, while rod-shaped and spiral bacteria are expressed in width x length. Moreover, there were differences in the measurement results of the size of the bacteria. In the dry state, it was shorter than the living bacteria, the liquid culture was larger than the solid culture, the young bacteria was larger than the old and mature bacteria, and the cell size became smaller when the medium's osmolarity increased. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
