The number of stomata was counted at each point, using a microscope with a lattice micrometer.
The distribution of the stomata could not be determined, but their polar axis lies along the length of the leaf.
The role of stomata in sensing and driving environmental change.
The stomata were observed to respond to changing ambient conditions within three minutes.
Stomata are present on some leaf fragments, but they are inconspicuous.
The stomata are sunken below the surface of the epidermis and are regularly aligned with their polar axis parallel to the length of the leaf.
The number of stomata per field was counted using a light microscope with ten replicas per leaf.
However, water loss can also occur across the trichomes and the cuticle when stomata are closed.
