C3 plants use C3 photosynthesis which uses CO2 in a 3-carbon compound and C4 plants use C4 photosynthesis which incorporates the CO2 in a 4-carbon compound. These compounds represent different types of sugar.Know More
Photosynthesis is the process of combining light and nutrients of the soil to create energy plants can use. C3 and C4 photosynthesis go about this process differently. Most plants are C3 types. The advantage with C3 photosynthesis is that it is more efficient than the C4 variety under normal light conditions since it requires fewer enzymes. C3 plants use C2, or Carbon.
Dioxide is used to create the 3-carbon compound G3P in order to produce usable energy. The higher CO2 concentration in C4 plants means that the stomata, the gas exchange part of the plant, do not need to open up to get any more, so less water is lost. C4 uses CO2 to create the 4-carbon compound oxaloacetate instead. C4 plants tend to do better in high oxygen environments. C4 plants also go through photosynthesis faster than C3 plants when there is a lot of light and heat nearby. Additionally, C4 plants have much better water efficiency than the C3 variety since they don’t have to keep their stomata open as much.
There are several thousand different types of C4 species with 19 different plant families. Examples include corn, saltbush and many plants that thrive during the summer months.Learn more about Botany
Starch formation in plants is a by-product of photosynthesis. Therefore, when a photosynthesis investigation is conducted the plant must be destarched in order to have a metric to determine if photosynthesis took place. The most common method of destarching a plant involves placing it in a dark setting for 24 to 48 hours.Full Answer >
For photosynthesis, plants use approximately 0.023 percent of sunlight energy. This is a very small percentage that plants need to make food when compared to the water cycle’s use of solar energy, which is 23 percent.Full Answer >
Photosynthesis is the process by which green plants manufacture their own food. The process takes place in small structures within the plant’s cells called chloroplasts. Photosynthesis evolved about 3 billion years ago, yet it remains the most important method for harvesting the sun’s energy on the planet.Full Answer >
Photosynthesis and chemosynthesis are similar in that they both provide for the process by which plants produce food and fuel for growth. However, they differ in terms of how they provide for this process. Photosynthesis accomplishes this process through sunlight, while chemosynthesis accomplishes it through chemical energy.Full Answer >
