Question: What do you call a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange, is part of the soil-plant-atmosphere continuum (SPAC),  the name of the pathway for water moving from soil through plants to the atmosphere
Sentence (from "Soil plant atmosphere continuum"): As water vapour transpires out of the leaf, further water molecules evaporate off the surface of mesophyll cells to replace the lost molecules since water in the air inside leaves is maintained at saturation vapour pressure.
