If you take a cross-section of a leaf and magnify it several times, you will see tiny pores on the underside. These holes are called stomata, and gaseous transfer takes place here, with carbon dioxide and oxygen entering and circulating inside the leaf. Waste gases from photosynthesis and respiration leave through the stomata as well. The oxygen diffuses out of the leaf because the concentration of oxygen is greater outside rather than inside the leaf (diffusion is the random movement of particles from an area of high concentration to an area of low concentration), down the concentration gradient. Likewise, the carbon dioxide diffuses into the cell because the concentration of carbon dioxide is greater outside the leaf than inside.
Stomata on the underside of the leaves.
To allow co2, h20 and o2 to move in and out of the leaf.
photosynthesis
all gases in the air near the leaf/plant/tree will pass through the stomata. the exchange of CO2 and O2 happens inside...
carbon dioxide and oxygen
plants maintain balance of co2 and o2 in the atmosphere..

Chloroplasts take up CO2 and give off O2.
Through the stomata
That's where the leaf uses sunlight to convert air (CO2) and water into sugar (and O2).

The gases get into your lung when you breathe.
what happens is we breath in o2 then we release carbon dioxide then the plants get co2 and release o2
Yes. As part of photosynthesis a plant converts carbon dioxide (CO2) to oxygen (O2).
In photorespiration, O2 replaces CO2 in a non-productive, wasteful reaction. Photorespiration occurs when the CO2 levels inside a leaf become low, which happens on hot dry days when a plant is forced to close its stomata to prevent excess water loss.
