comics about photosynthesis

Well, in simple terms, photosynthesis is a process in plants. Chlorophyll in the plant's cells absorbs sunlight. Then, carbon dioxide from the air and water from the roots are used. The energy from the sunlight is used to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. The oxygen is then released into the atmosphere as a by - product.

In simple terms, plants take in carbon dioxide from the air and water from the soil. The energy from the sun is captured by special pigments. Through a series of chemical reactions, the plant makes its own food (glucose) and releases oxygen as a by - product.

The overall importance of photosynthesis is huge. It not only produces oxygen that is essential for most living organisms on Earth, but also provides the basis for the food chain as plants are the primary producers.

In more detail, the light - dependent reactions occur first. Here, light energy is converted into chemical energy in the form of ATP and NADPH. These are used in the light - independent reactions (Calvin cycle). In the Calvin cycle, carbon dioxide is fixed and reduced to form glucose. It's a complex but vital process for life on Earth as it provides oxygen and is the basis of the food chain.

The second part is the light - independent reactions, also known as the Calvin cycle. Here, carbon dioxide from the air is taken in. Using the energy and hydrogen ions from the light - dependent reactions, carbon dioxide is converted into glucose, a type of sugar that plants use for energy and to build other molecules.

1. ** Solution to the calculation of photosynthesis rate ** - When it came to the calculation of photosynthesis rate, the relationship between actual (true) photosynthesis rate, net (apparent) photosynthesis rate, and respiratory rate should be made clear. The actual photosynthesizing rate = net photosynthesizing rate + respiratory rate. - For example, when calculating the relevant amount of carbon dioxide, the actual assimilation of carbon dioxide = the actual absorption of carbon dioxide + the release of carbon dioxide. - For the calculation of oxygen, the actual O2 release from photosynthesis = the actual (apparent photosynthesis) O2 release + the absorption of oxygen from the respiratory rate. - When calculating the amount of sugar, the net production of sugar from photosynthesis = the actual production of sugar from photosynthesis minus the consumption of sugar from respiration; the net organic matter (accumulation)= the actual production of organic matter (photosynthesis) minus the consumption of organic matter (respiration). - When calculating the combination of the two types of breathing, one must first determine the conditions of the breathing type. Under the condition of sufficient oxygen, the amount of oxygen absorbed and the amount of CO2 released were equal. Under the condition of absolute oxygen deficiency, only the oxygen deficiency could be carried out. Under the condition of oxygen deficiency, both oxygen and oxygen deficiency could be carried out. The amount of oxygen absorbed and the amount of CO2 released were not necessarily equal. When solving the problem, one must first write and balance the reaction formula correctly. Secondly, one must distinguish the source of the CO2 and then calculate it (how much CO2 is produced by both the oxygen and the oxygen breathing). 2. ** Solution to the concept map or relationship problems of photosynthesis and respiration ** - It should be clear that the raw materials of photosynthesis were carbon dioxide and water, the products were organic matter and oxygen, and the location was the plastids. Respocation was a process in which cells used oxygen to decompose organic matter into carbon dioxide and water, and released the energy stored in organic matter for life activities. The location was mainly in the mitochondria. The two were independent and dependent on each other. Photosynthesis provided the material basis for respiration, and respiration provided the raw materials for photosynthesis. - For example, when filling in the blanks in the concept map, he would fill in the blanks based on his understanding of the concepts, raw materials, products, locations, and so on. 3. ** About the solution to the biology problem of photosynthesis ** - When measuring the breathing rate: - In terms of equipment, the commonly used equipment was to use the solution of <anno data-annotation-id ="00000440 - 4000 - 4000 - 8000 - 8000 - 90000000000"></anno> to absorb </anno></anno> and observe the amount of </anno></anno> absorbed in the unit time or the change in the pressure in the container (such as the movement of water droplets in the scale tube) to indicate the breathing rate. - Pay attention to error correction. If the experimental material is a green plant, the entire device should be shielded from light, otherwise the photosynthesis rate will interfere with the detection of the respiratory rate. If the seeds are selected as experimental materials, the existence of microorganisms must be considered to interfere with the detection of the experiment. Therefore, the device and the tested seeds should be disinfected. In order to avoid errors caused by physical factors such as air pressure and temperature during the experiment, a control experiment should be set up. The tested biological materials should be deactivated (such as cooking the seeds), and other conditions should remain unchanged. - When measuring the photosynthesis rate: - Using the solution of NaOx to absorb the CO2 in the container, the cell's respiratory rate could be measured by the change of oxygen. Using the decomposition of NaHCO3 to produce carbon dioxide to ensure the stability of carbon dioxide in the container, the increase of oxygen in the container could be measured to obtain the plant's net photosynthesis rate. - When analyzing the experiment results: - For example, in the experiment of "Green leaves produce organic matter under light", the purpose of placing the plant in the dark for a day and night was to deplete the original starch in the leaves; covering the leaves with black paper was to set up a control experiment; and the leaves were heated in alcohol with water to dissolve the photosynthesis in the alcohol. Then, according to the color development of the different treatment groups (such as the shaded and non-shaded parts) after dripping the solution, the conditions of photosynthesis (such as light), products (starch), etc. were analyzed. For the comparison of multiple sets of experiments (such as different leaf treatments), the impact of each experimental variable on photosynthesis should be analyzed, such as the impact of a lack of a certain raw material (such as carbon dioxide) on the production of photosynthesis products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There was a little seed. It was planted in the ground by a kind child. This seed grew into a small plant called Greenie. Greenie was very curious. One day, it noticed the sun shining brightly above. It turned out that this was a very important thing for Greenie. Through photosynthesis, Greenie's leaves, which were like little solar panels, captured the sunlight. The plant also took in carbon dioxide through its tiny pores. With the help of the sun's energy, it combined the carbon dioxide with water from the roots. This made food for Greenie in the form of sugar. And at the same time, oxygen was sent out into the air. Greenie was happy to be part of this amazing cycle of life.

In plants, photosynthesis starts with the absorption of light by chlorophyll. This light energy is then used to power a series of chemical reactions. The plant takes in carbon dioxide through small pores called stomata on the leaves. Water is transported up from the roots. The energy from the sunlight is used to combine carbon dioxide and water in a way that creates glucose, a valuable source of energy for the plant. The oxygen that is produced as a result is released, and this process is essential for the plant to survive and thrive, and it also has a huge impact on the global carbon - oxygen cycle.

Once upon a time, there was a little leaf named Lily. Lily lived on a big green tree. The sun would shine its warm rays every day. Lily and her leaf friends knew that with the help of the sun, they could do something amazing - photosynthesis. They took in carbon dioxide from the air through their tiny pores. The sunlight provided the energy they needed. Then, using water that the tree roots sucked up from the ground, they combined these things and made food for the tree. And as a by - product, they released oxygen into the air, which all the animals around needed to breathe.
