Carbon dioxide and oxygen enter and leave the plant through the stomata, on the underside of leaves.
guard cells and stomata.
to allow the correct amount of oxygen to enter and leave the substance
The element is carbon. Organic chemistry revolves around carbon-containing compounds that have C-C or C-H bonds. Not all compounds that have carbon are classified as organic though, such as carbon dioxide.
You can, the dry ice(solid form of carbon dioxide) will ultimately evaporate into carbon dioxide gas, and will then leave only the regular ice (frozen water). Because the dry ice will no longer exist, the regular ice will melt.

guard cells and stomata.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
There are a number of gases that enter and leave the lungs - predominantly, humans Inspire (Breathe in) Oxygen and Expire (Breathe out) Carbon Dioxide. soo that is the answer init lool x
Oxygen (O2) and Carbon Dioxide (CO2) =)
Diffusion
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
plants take in carbon dioxide and release oxygen
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
stomata
Guard cells allows the exchange of oxygen and carbon dioxide in and out of the leaf. This is known as leaf exchange. When guard cells are full of water they swell up and close meaning no oxygen can leave or carbon dioxide can enter, but when the water is taken away from the cell they open up to allow oxygen to exit and carbon dioxide to enter.
