Plants use energy from light to convert water and carbon dioxide into sugar and oxygen in a process called photosynthesis. Chlorophyll, the green pigment in leaves, absorbs sunlight and uses the energy to convert six molecules of carbon dioxide and six molecules of water into one molecule of sugar and six molecules of oxygen. Plants use the sugar to grow and release the oxygen back into the atmosphere. They also help regulate the amount of carbon dioxide, which is one of the most important greenhouse gases, in the atmosphere. Plant leaves have small openings, called stomata, all over their surfaces. The stomata open to absorb the carbon dioxide needed to perform photosynthesis. They also open to release the oxygen produced by this process.

Trees are commonly chopped down and processed for wood and paper, but the enduring value of trees comes from their ability to turn the sun's energy into oxygen, sustaining all human and other animal life on Earth. Advocates against deforestation warn that the consumption of trees for industrial purposes threatens the delicate balance necessary for this chemical process to take place. The unique chemical process that trees and plants use to turn light energy from the sun into oxygen is known as photosynthesis. The production of oxygen is a beneficial result of photosynthesis, but it is not the main purpose of this process. In fact, oxygen is simply a byproduct. Plants create their own food through photosynthesis.

By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. However, the process is not exactly this simple.

Can sleeping in a room full of plants can be dangerous? A common myth states that, at night, plants compete with people for oxygen! All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is carbon dioxide. In other words, respiration is the opposite of photosynthesis. However, during the day, the amount of oxygen plants release as part of photosynthesis makes the amount of oxygen they consume for respiration seem negligible.

Unlike photosynthesis, in which plants absorb carbon dioxide and release oxygen, respiration reverses it. And plants respire constantly. Much of the CO2 plants take from the atmosphere for photosynthesis finds its way back via respiration from plants and soil. SERC photo. In a high-CO2 experiment, plants released roughly 10 percent less CO2. It was also significant enough to provoke controversy when Drake and his colleagues reported it in , partly because no one could explain how it was happening.

The strange, controversial way plants trap CO2

Updated November 22, New research suggests plants could be releasing more carbon dioxide into the atmosphere than previously thought. A study involving the Australian National University, Western Sydney University, and centres around the world has found plants release more carbon dioxide through their respiration. And as global temperatures rise, scientists say the output of carbon dioxide by plants will accelerate. During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.
