0 one of the many pores (= very small holes in the surface) on a leaf or stem of a plant through which gases are able to pass in and out -- （植物葉子或莖表面的）氣孔
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.
In the adult worm, this papilla becomes dome-shaped with a small central stoma.
The role of stomata in sensing and driving environmental change.
The stomata were observed to respond to changing ambient conditions within three minutes.
A distal stoma allows bowel function to recover.
However, water loss can also occur across the trichomes and the cuticle when stomata are closed.
This was also true for the upper epidermis of tannia and sweet potato where stomata were present.
