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. Plant leaves are also able to absorb and release water through the stomata. Trees namely Common Horse-chestnut, Black Walnut, American Sweetgum, Ponderosa Pine, Red Pine, White Pine, London Plane, Hispaniolan Pine, Douglas Fir, Scarlet Oak, Red Oak, Virginia Live Oak and Bald Cypress are found to be good at absorbing and storing CO2. But Cavanagh is hopeful, and notes that as the global climate warms, finding a way to solve for photorespiration will be ever more dire: Right now, plants are absorbing around one-third of the excess carbon dioxide humans are pumping into the atmosphere, and turning it into sugars to grow. For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. During photosynthesis, the oxygen gas produces goes out through the leaves of the stomatal pores. A final question that has periodically intrigued researchers is whether plants take up carbon through their roots in addition to through their leaves. Nevertheless, it is abundantly evident that plant roots, like most other plant organs, typically do better in CO2-enriched air than in current ambient air.

While oak is the genus with the most carbon-absorbing species, there are other notable deciduous trees that sequester carbon as well. The common horse-chestnut (Aesculus spp. ), with its white spike of flowers and spiny fruits, is a good carbon absorber.

Fast growing trees like ash, poplar, willow etc produce most oxygen - because the amount of oxygen produced depends on the amount of carbon sequestered. Trees which produce more oxygen (because of their ability to produce oxygen even at night) are: Neem. Peepal. Areca palm.

Other natural phenomenon may help to cool the planet: Some researchers believe that phytoplankton — microscopic plants that drift on ocean currents — may reduce carbon dioxide levels in the atmosphere and lower the atmosphere's temperature.

Photosynthesis, the process through which plants use light to create food, requires carbon dioxide. CO2 concentration in ambient air ranges from 300-500 parts per million (ppm), with a global atmospheric average of about 400 ppm.

Carbon is also found in soil from dead and decaying animals and animal waste. Carbon is found in the biosphere stored in plants and trees. Plants use carbon dioxide from the atmosphere to make the building blocks of food during photosynthesis. Carbon is found in the hydrosphere dissolved in ocean water and lakes.

In the process of photosynthesis, phytoplankton release oxygen into the water. Half of the world's oxygen is produced via phytoplankton photosynthesis.

Lithium hydroxide. Other strong bases such as soda lime, sodium hydroxide, potassium hydroxide, and lithium hydroxide are able to remove carbon dioxide by chemically reacting with it. In particular, lithium hydroxide was used aboard spacecraft, such as in the Apollo program, to remove carbon dioxide from the atmosphere

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.

More CO2 generally leads to higher rates of photosynthesis and less water consumption in plants. So, at first sight, it seems that CO2 can only be beneficial for our plants. But things are a lot more complex than that.

Studies have shown that increased concentrations of carbon dioxide increase photosynthesis, spurring plant growth. While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change.

One of the first things taught in biology class is that animals breathe in oxygen and exhale CO2, while plants take in CO2 during the day and release oxygen. In a process called “photosynthesis, ” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen.

https://www.sciencedaily.com/terms/carbon_dioxide.htm

Plants convert carbon dioxide to oxygen during a process called photosynthesis, using both the carbon and the oxygen to construct carbohydrates. In addition, plants also release oxygen to the atmosphere, which is subsequently used for respiration by heterotrophic organisms, forming a cycle.

Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet. Plant leaves have tiny vents called stomata that open or close to let the plant breathe.

The Short Answer: Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to Earth. It helps Earth hold the energy it receives from the Sun so it doesn't all escape back into space. If it weren't for carbon dioxide, Earth's ocean would be frozen solid.
