Stomata are tiny pores or holes found to be present in the epidermis of leaves. Many plant cells maintain turgor pressure at remarkable constant levels in the face of large changes in the tonicity of the fluids in their immediate environment by changing the somatic pressure of the cytoplasm and vacuole—in part by controlled breakdown and resynthesis of polymers such as polyphosphate in the vacuole, and in part by altering.
