| This capacity is due to the presence of stomates on both leaf surfaces, permeability of tissues for CO 2 diffusion and an intense Rubisco activity. |
|
| Some starch can also be seen in the guard cells of stomates. |
|
| This makes it unlikely that stomates closed because of a leaf water deficit and raises the possibility of regulatory signals coming from the roots. |
|
| Blackbrush leaves are hypostomatic, implying that stomates are located on the abaxial epidermis only. |
|
| Solid particles, clogging the stomates of leaves or needles modify the transpiration rate and reduce the intensity of photosynthesis. |
|
| When the stomates are open, carbon dioxide is absorbed from the air. |
|
| One of the ways that crops respond to water stress is to close their stomates, which results in reduced water evaporation and increased temperature of the crop canopy. |
|
| Krizek and Semeniuk discovered that the fewer stomates a plant has, or the smaller the stomate openings, the more it can resist damage from pollutants. |
