In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems.
In aquatic plants, gas exchange directly though the tissue surface.
Stomata (stoma)
Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
The system by which gases enter and leave the body is called the respiratory system. It includes organs such as the lungs, nose, and trachea that work together to allow for the exchange of oxygen and carbon dioxide between the body and the environment.
The process is called gas exchange, and it mainly occurs through small openings called stomata on the leaves of plants. These stomata open and close to regulate the exchange of gases like oxygen, carbon dioxide, and water vapor between the plant and its surroundings.
Plants take in air through tiny pores on their leaves called stomata. These stomata open to allow for the exchange of gases such as carbon dioxide and oxygen during photosynthesis and respiration.
Gases can enter the atmosphere through natural processes like volcanic eruptions and biological decay, as well as human activities such as burning fossil fuels and industrial processes. Gases leave the atmosphere through processes like photosynthesis, where plants absorb carbon dioxide, and through chemical reactions that remove gases from the air. Wind and precipitation can also play a role in removing gases from the atmosphere.
Simple diffusion.

Oxygen (O2) and Carbon Dioxide (CO2) =)
gases doesnt enter the planet
Plants. By allowing gases to enter and exit through stomata, plants can exchange gases needed for respiration, such as oxygen and carbon dioxide, with the external environment. This adaptation helps plants survive by facilitating the exchange of gases required for cellular respiration and photosynthesis.
pores in the leaves and stomates allow gases to enter and leave the plant
The openings in leaves that allow gases to pass through are called stomata. Stomata help regulate gas exchange by allowing carbon dioxide to enter the leaf for photosynthesis and oxygen to exit, while also enabling water vapor to escape through transpiration.
