Photosynthesis is the most important procedure in all plants and trees, as it helps them create energy, which in turn assists them in performing various cellular activities. These activities play a major role in the growth and evolution of plants and trees. Here in this section, we will provide a comprehensive description of the process of photosynthesis and its importance and various aspects. Also, the article covers photosynthesis diagrams with explanations.<\/p>\n
As a student, we all must have been extensively exposed to the term, photosynthesis. With an interesting dimension of energy generation, the process of photosynthesis always remained an important topic of study.<\/p>\n
Photosynthesis is defined as the process of conversion of light energy to chemical energy, which in turn is used in performing various cellular activities. This process is commonly observed in phototrophs, and all the chemical energy formed by the process is stored in the form of sugars.<\/p>\n
Moreover, the Photosynthesis process is made possible because of special pigments such as chlorophyll a, chlorophyll b, xanthophyll, and carotene. Besides, the photosynthesis process occurs in the Chloroplast of cells, and it involves the absorption of carbon dioxide and water, and converting them to glucose, and oxygen in the presence of sunlight.<\/p>\n
In this section, we will talk about the various characteristics of the photosynthesis process, \u00a0with brief explanation and details:<\/p>\n
to begin with, photosynthesis also happens in organisms other than green plants. These can be cyanobacteria, green sulfur bacteria, and purple bacteria.<\/p>\n
Coming back to the photosynthesis process in plants, the basic process refers to its occurrence when plants make use of light energy and convert carbon dioxide and water into glucose and oxygen respectively. The leaves in plants have organelles called chloroplasts which are instrumental in undertaking photosynthesis.<\/p>\n
Typically, the process of photosynthesis is as follows:<\/strong><\/p>\n Equation of Photosynthesis<\/span><\/b><\/p>\n The process of Photosynthesis can be explained by the equation,\u00a0<\/span>\u00a0<\/span><\/p>\n 6CO<\/span><\/b>2<\/span><\/b>\u00a0\u00a0\u00a0 +\u00a0\u00a0 6H<\/span><\/b>2<\/span><\/b>O\u00a0 \u2014>\u00a0 C<\/span><\/b>6<\/span><\/b>H<\/span><\/b>12<\/span><\/b>O<\/span><\/b>6<\/span><\/b>\u00a0 + 6O<\/span><\/b>2\u00a0\u00a0<\/span><\/b>\u00a0<\/span><\/p>\n The Photosynthesis process is an endothermic reaction, and the above equation explains how the photosynthesis process works. Firstly, carbon dioxide, and water molecules, are converted into glucose and oxygen in the presence of sunlight.<\/p>\n In summary, the photosynthesis process features two reactants, carbon dioxide and water that turn into oxygen and glucose, respectively.<\/p>\n As explained, certain bacteria too practice photosynthesis but they do not produce oxygen as the by-product of photosynthesis. These are called anoxygenic photosynthetic bacteria, while the bacteria that produce oxygen as a by-product are called oxygenic photosynthetic bacteria.<\/p>\n Now that you have a good understanding of the Photosynthesis process and the equations. Let us now talk about the various steps involved in this process. <\/span>\u00a0<\/span><\/p>\n As the title states, here you will learn about the importance of the Photosynthesis process for plants and trees, such as,\u00a0<\/span>\u00a0<\/span><\/p>\n Location of photosynthesis<\/strong><\/p>\n In plants and green algae, the photosynthesis process occurs in chloroplasts, as explained in the earlier sections. Chloroplasts, which are green plastids, can be found in stems, leaves, and floral parts. Let us note that these cell organelles are present only in plants, in the mesophyll of leaves.<\/p>\n Please check the photosynthesis diagram for more<\/strong><\/p>\n Are there any factors that influence the process of photosynthesis?<\/strong><\/p>\n Certain factors affect the photosynthesis process. These can be:<\/p>\n Structure of Photosynthesis<\/strong><\/p>\n The green pigment called Chlorophyll is found in the chloroplasts of the plant cell and the mesosomes of cyanobacteria. This pigment performs the most crucial job in the photosynthesis process. If you notice the structure of photosynthesis, it allows the plants to absorb energy from sunlight.<\/p>\n The chlorophyll is made up of chlorophyll-a and chlorophyll-b.<\/p>\n Other organisms that perform photosynthesis can also have chlorophyll in the form of chlorophyll-c1,\u00a0 chlorophyll-c2,\u00a0 chlorophyll-d and chlorophyll-f.<\/p>\n The typical structure of chloroplasts consists of:<\/strong><\/p>\n The photosynthesis process can happen in two stages:<\/p>\n Light reaction<\/p>\n Dark reaction<\/p>\n In this, the Photosynthesis process takes off as the light reaction that can be possible only during the day when the sun is present. In the case of plants, this light-dependent reaction happens inside the thylakoid membranes of chloroplasts.<\/p>\n There is Grana, a membrane-bound structure that resembles a sac. This structure is present inside the thylakoid and its role is to gather the light, and this is called photosystems.<\/p>\n The photosystems feature large bases of pigments and protein molecules that are present within the plant cells. These are instrumental during the process of light reactions in the photosynthesis process.<\/p>\n The photosystems are again classified into Photosystem I and Photosystem II.<\/p>\n In the case of light-dependent reactions, the light energy is converted to ATP and NADPH. These are eventually useful during the second phase of the photosynthesis process.<\/p>\n As the light reactions take place, ATP and NADPH are generated by two electron-transport chains, where water is used and oxygen is produced.<\/p>\n The chemical equation of the light reaction of photosynthesis comes down to:<\/p>\n 2H2O + 2NADP+ + 3ADP + 3Pi \u2192 O2 + 2NADPH + 3ATP<\/p>\n As the expression suggests, this reaction is independent of the presence or availability of light.<\/p>\n This is called the dark reaction or carbon-fixing reaction.<\/p>\n This dark reaction happens inside the stroma of the chloroplast where the NADPH and ATP products are used from the light reaction.<\/p>\n In this light-independent process, sugar molecules are formed out of the water and carbon dioxide molecules.<\/p>\n Plants attract carbon dioxide from the atmosphere through stomata and proceed to the Calvin photosynthesis cycle.<\/p>\n Under the Calvin cycle, the ATP and NADPH that have formed during the light reaction trigger the reaction and convert six molecules of carbon dioxide into a single sugar molecule or glucose.<\/p>\n The chemical equation for the light-independent reaction can be brought down to:<\/p>\n 3CO2 + 6 NADPH + 5H2O + 9ATP \u2192 G3P + 2H+ + 6 NADP+ + 9 ADP + 8 Pi<\/p>\n Calvin Cycle<\/strong><\/p>\n The Calvin cycle is a light-independent reaction and its entire process occurs in the stroma of the chloroplasts.<\/p>\n We have helped you understand all about the Photosynthesis equation and the Photosynthesis process.
