This is because when a tree is cut down, the CO2 within it in released. On top of that, because the tree has been cut down, it can no longer use up CO2 from the atmosphere for photosynthesis. In conclusion, deforestation has the effect of releasing more CO2 into the air and also limiting the amount of CO2 being absorbed by trees (because it reduces the number of trees).
Answer:
Gas exchange happens in the spongy mesophyll tissue of the leaf. Spongy mesophyll cells are covered by a thin layer of water and loosely packed. When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of it.
