Respiration, in which energy is released from carbohydrates for metabolic needs, takes place in plants through a process which can be expressed in a word equation as: glucose + oxygen = energy + carbon dioxide + water. The chemical equation for this process can be expressed as: C6H12O6 + 6O2 = energy + 6CO2 + 6H2O. Respiration, which is a breaking-down process that releases energy, can be viewed as the opposite of photosynthesis, which is a building-up process that takes in energy in the form of light and uses it to produce carbohydrates.Know More
The process by which plants respire, or release energy from carbohydrates, is similar to the process that occurs in oxygen-breathing animals. Respiration in both animals and plants is also similar to oxidation, in which heat is released by burning a fuel such as wood. Although plants require carbon dioxide to produce carbohydrates through photosynthesis, they also use oxygen to perform respiration.
When oxygen is unavailable or limited, plants can release energy from stored carbohydrates through anaerobic respiration, which takes place through fermentation in plants. In its scientific sense, fermentation refers to a metabolic process that is capable of releasing energy from an organic molecule and does not require oxygen. Instead of creating the byproducts of carbon dioxide and water, the release of energy through fermentation creates the byproducts of lactic acid or ethyl alcohol, along with carbon dioxide.Learn more about Botany
Transpiration is the process in which a plant releases water vapor from its leaves into the surrounding air. The rate transpiration occurs varies widely based on the weather and soil conditions surrounding the plant.Full Answer >
Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.Full Answer >
Glucose is important to plants because it is a source of energy that can be converted into other components like starch or cellulose; these components are necessary for cell structures such as the cell walls and for the plant's development. Glucose is also necessary for respiration in plants.Full Answer >
In oxygenic photosynthesis, cyanobacteria and the chloroplasts of plants and algae turn carbon dioxide, water and photons into carbohydrates and free oxygen. Only some of this oxygen is used by the organism; the rest is released into the atmosphere.Full Answer >
