Carbon Dioxide
carbon dioxide
Oxygen. Because the plants need sunlight to produce it.

Carbon Dioxide(Co2)
The easiest way is to use an aquatic plant (one that grows underwater). In sunlight this will release bubbles - collect the bubbles in an upturned (water filled) jar placed over the plant. Once you have collected the gas use the oxygen test (relight a smoldering taper) on the gas to see if it is oxygen.
Carbon Dioxide
Humans primarily release carbon dioxide (CO2) as a waste gas when exhaling. Other gases that may be released as waste by humans include methane and ammonia.
A plant releases oxygen gas (O2) through its stomata during photosynthesis. This oxygen is a byproduct of the process in which carbon dioxide is converted into glucose with the help of sunlight.
Nitrogen gas is released through various natural and human processes. In nature, it is primarily released during the decomposition of organic matter, where bacteria convert nitrogenous compounds into nitrogen gas, a process known as denitrification. Additionally, human activities such as the combustion of fossil fuels and the use of nitrogen-containing fertilizers can also lead to the release of nitrogen gas into the atmosphere.
A plant with open stomata is allowing for gas exchange to occur. This includes the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. Additionally, it enables transpiration, which helps in cooling the plant and transporting nutrients and water throughout its system.
Neptune is neither a rocky nor a gas plant! It is a gas planet, though.
During photosynthesis, plants release oxygen gas as a byproduct. This occurs when plants take in carbon dioxide from the environment and, through the process of photosynthesis, convert it into glucose and oxygen.
