The air inside the lungs is never replaced completely. 1500 ml of air is always present in the lungs. Therefore,gaseous exchange continues in the lungs even during expiration .
Diffusion
Because to carry out the process of diffusion of gas.
Although not necessary, the stomata during gaseous exchange also favour transpiration and provide passage to the microorganisms.
thru their leaves. Edited answer: Partly from the process of photosynthesis during day time and partly from the air through the stomata during gaseous exchange.
It provides O2 and eliminates CO2 during respiration, It is essential for photosynthesis as it provides CO2 o plants .
pressure in the lungs forces air to leave the site of gaseous exchange and the diaphragm pushes up forcing the person to exhale.

Transpiration in green plants takes place through the stomata and cuticle. The stomata perform the function of gaseous exchange and during this process water vapours also get transferred due to difusion.
Respiration is the process of gaseous exchange by: External breathing, the oxygen is taken up by the capillaries of the lung alveoli(air sacs) and expelled as carbon dioxide which is released from the blood. Internal, the stage of respiration in which oxygen is released to the tissues and carbon dioxide absorbed by the blood.Visualise the lungs as upside downtreesand the alveolias leaves.
