The first image shows the picture of the internal structure of the leaf. It is a transverse section of a leaf. It shows structures in the following sequence epidermis, mesophyll cells and vascular bundles.Note -Kindly repost the remaining question next time.Exchange of gases, that is, taking in of carbon dioxide for photosynthesis and transporting oxygen to outside which is a by product of photosynthesis is performed by stomatal apertures present on one of the surface or both the surfaces of the leaf. The stomatal apparatus consists of an aperture and is surrounded by guard cells which build up pressure inside by accumulating fluid and help to open the pore through which gaseous exchange takes place. When the guard cells are in flaccid state the stomatal pores remains closed and no gaseous exchange takes place.
