What is Photorespiration?
Photorespiration is the process of photosynthesis that uses oxygen and produces carbon dioxide. The plant takes in carbon dioxide and sunlight to create glucose and oxygen. The oxygen is released back into the atmosphere and the glucose is used by the plant to create energy.
Photorespiration in C3 Plants
Photorespiration is a process that helps C3 plants get rid of the excess carbon dioxide they take in during photosynthesis. The carbon dioxide is converted into a gas called carbon monoxide, which is then released into the atmosphere.
Photorespiration in C4 plants
In photorespiration, C4 plants use a different enzyme, PEPcase, to fix carbon dioxide in the presence of oxygen. The carbon dioxide is combined with phosphoenolpyruvate (PEP) to form oxaloacetate. The oxaloacetate is then converted to malate, which is transported to the mitochondria, where it is converted back to carbon dioxide and PEP. The carbon dioxide is then used to fix more glucose in the Calvin cycle.
Detailed Difference between C3 and C4 Plants
C3 plants and C4 plants are two different types of plants that have different mechanisms for photosynthesis. C3 plants have a more inefficient process for photosynthesis that results in them producing less sugar than C4 plants. C4 plants have a more efficient process for photosynthesis that results in them producing more sugar.
C3 and C4 plants are two different types of plants that have different ways of photosynthesizing. C3 plants are the most common type of plants and they include most of the plants that we eat, such as wheat, rice, and potatoes. C4 plants are less common and include plants like maize and sugarcane. C4 plants are more efficient at photosynthesis than C3 plants, which is why they are able to grow in drier climates.
C3 plants use the Calvin cycle to photosynthesize. During the Calvin cycle, carbon dioxide is converted into sugar. The sugar is then used to produce energy for the plant. C4 plants use a different process called the Hatch-Slack cycle to photosynthesize. During the Hatch-Slack cycle, carbon dioxide is converted into a four-carbon molecule. The four-carbon molecule is then used to produce energy for the plant.
One of the reasons that C4 plants are more efficient at photosynthesis is that they can close their stomata when it is hot or dry. This prevents the plant from losing water. C3 plants cannot close their stomata and they lose water through their leaves. This is why C3 plants are not able to grow in drier climates.
Explain in detail :
C3 and C4 plants are two different types of plants that have evolved to deal with different environmental conditions. C3 plants are the most common type of plant, and they use the Calvin cycle to fix carbon dioxide into organic molecules. C4 plants are less common, but they are more efficient at fixing carbon dioxide because they use a different mechanism to concentrate carbon dioxide in their cells.
One of the differences between C3 and C4 plants is their ability to fix carbon dioxide in the presence of oxygen. C3 plants can only fix carbon dioxide in the absence of oxygen, while C4 plants can fix carbon dioxide in the presence of oxygen. This difference is due to the way that C3 and C4 plants use carbon dioxide in the photosynthesis process.
C3 plants use the Calvin cycle to fix carbon dioxide into organic molecules. In the Calvin cycle, carbon dioxide is fixed into a 3-carbon molecule called 3-phosphoglycerate. This 3-carbon molecule is then used to make glucose and other organic molecules.
C4 plants use a different mechanism to fix carbon dioxide into organic molecules. In C4 plants, carbon dioxide is fixed into a 4-carbon molecule called oxaloacetate. This 4-carbon molecule is then used to make glucose and other organic molecules.
The ability to fix carbon dioxide in the presence of oxygen is an important difference between C3 and C4 plants. C3 plants can only fix carbon dioxide in the absence of oxygen, while C4 plants can fix carbon dioxide in the presence of oxygen. This difference is due to the way that C3 and C4 plants use carbon dioxide in the photosynthesis process.
