WebThe mesophyll contains palisaded cells and spongy parenchyma. The palisaded cells are tightly packed, and they help in photosynthesis. On the other side, the spongy parenchyma contains air spaces. These air spaces allow gaseous exchange between the leaf and the outside environment. Both these layers contain many chloroplasts. WebThe control of gaseous exchange between the leaf and external atmosphere is governed by stomatal conductance ( gs ); therefore, stomata play a critical role in photosynthesis and transpiration and overall plant productivity. Stomatal conductance is determined by both anatomical features and behavioral characteristics. chinese new year 2023 early years
