Plants require carbon dioxide for growth. It is a necessary ingredient for photosynthesis in which the plant creates glucose and structural carbon that forms the plant body. According to Nature Education, approximately 96 percent of the typical dry plant mass is due to compounds created through photosynthesis using carbon dioxide.Continue Reading
While the human-caused increase in carbon dioxide receives the blame for global warming, it also impacts plant growth. Experiments by Nature Education show most of the benefits to be positive in plant growth. Increasing carbon dioxide concentration increases the rate of growth for most, but not all plants. In addition, the amount of fruit the plant produces increases. The plants absorb carbon dioxide through the stoma of the leaves. However, opening the stoma increases transpiration, or water loss, for the plant. Most plants regulate the time the stoma are opened to conserve water. In atmospheres with greater concentrations of carbon dioxide, the plant is able to absorb more of the gas while still limiting water loss, increasing growth rate.
Growth of plants depends on more than just carbon dioxide. The plants need minerals and water to sustain the growth process. An increase in carbon dioxide concentrations in the air does not necessarily mean these other requirements are available. Thus, while increasing carbon dioxide encourages greater growth, it does not guarantee it.Learn more about Botany
The two gases that move in and out of the stomata on plant leaves are carbon dioxide and oxygen. The exchange of these two gases plays a vital role in photosynthesis, which is the process by which plants use light to produce and store the energy they require for their metabolic needs. In addition to light, carbon dioxide and water are required for this process to occur, and oxygen is a byproduct.Full Answer >
The function of chloroplasts is to convert sunlight, water and carbon dioxide into food for the plant. Chloroplasts are energy organelles, and are present in all types of plants.Full Answer >
A stomata is the part of a plant that allows gases such as oxygen and carbon dioxide to move freely into and out of a leaf. Every plant with above-ground leaves has stomata.Full Answer >
Human activity impacts the carbon cycle by introducing more carbon dioxide into the atmosphere: carbon dioxide accumulates in the atmosphere, changes temperatures and alters the salinity levels of oceans, disturbing the salt and water balance equilibrium that supports proper growth of marine plants and animals. Some carbon dioxide generation occurs naturally, although human actions, such as burning fossil fuels and operating factories, accelerate its creation and escape into Earth's natural environments. This translates to warmer air temperatures and higher acidity levels in water bodies.Full Answer >
