| Fluorescence of guard cell chloroplasts was imaged when plants were at approximately the six-leaf stage. |
| The guard cell cannot expand because it is held tight in its cellulose ring. |
| The inner anticlinal wall of the guard cell is the ventral wall. |
| In the paradermal sections, the cuticle, guard cell length and epidermal cell shapes were examined. |
| Cellulose microfibrils within the guard cell wall are considered radial if they are oriented in the same way as the dotted lines. |
| The details of guard cell wall composition and organization are, unfortunately, not known. |
