The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. Each stoma is surrounded by a pair of specialized, kidney shaped cells called guard cells, which possess chlorophyll and regulate the opening and closing of stomata. 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. Unfortunately for the plant, if stomata are open to allow carbon dioxide into the leaf, they will also allow water vapour to leave. short note on the role of stomata in plants or leaf , with diagram - Science - Life ... note on the role of stomata in plants or leaf , with diagram.
