WebLeaves contain Stomata; these are small holes found distributed throughout the leaf which open and close, allowing gas exchange. Cells are organised in layers within the leaf. There are air spaces in spongey mesophyll layer which allows gases to effectively diffuse through the leaf. Finally the cells are moist which aids in gas exchange. WebPlant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem.
