| 11. | Accumulation of these hormones appears to cause increased stomatal density such as when the plants are kept in closed environments.
|
| 12. | The upper surface of the leaves is green and shiny, while the undersides have 2 wide silvery stomatal bands.
|
| 13. | The leaves are linear, long and wide, glossy green above, and with two white stomatal bands below.
|
| 14. | He demonstrated the link between forests and the atmosphere using novel techniques for measuring leaf water potential and stomatal conductance.
|
| 15. | The leaves have two whitish lines on the bottom, each of which is formed by wax-covered stomatal bands.
|
| 16. | The stomata are usually restricted to the abaxial or underside of the leaf, forming two stomatal bands around the midrib.
|
| 17. | Potassium channels and pumps have been identified and shown to function in the uptake of ions and opening of stomatal apertures.
|
| 18. | It is thought that plant hormones, such as ethylene and cytokines, control the stomatal developmental response to the environmental conditions.
|
| 19. | The stomatal armature contains one dorsal tooth and two subventral teeth, while the wall may additionally contain rows of small denticles.
|
| 20. | The needles are 1 2.8 cm long, pruinose, with stoma-lines above and 2 stomatal bands below.
