The mesophyll cells of plants not pretreated with HA were markedly damaged following chilling stress. The chloroplasts appeared irregular in shape, the arrangement of the stroma lamellae was disordered, and no starch ... 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.

Mesophyll resistance, r m (or its reciprocal, mesophyll conductance, g m), reduces the rate at which Rubisco can fix CO 2, increasing the water and nitrogen costs of carbon acquisition. g m varies in proportion to the surface area of chloroplasts exposed … WebVerified questions.
