Moss stomata do not respond to light and CO2 concentration but facilitate carbon uptake by sporophytes: a gas exchange, stomatal aperture, and 13C- labelling study (vol 230, pg 1815, 2021)

Summary: The study found that stomata in moss sporophytes play an important role in CO2 assimilation and water exchange, which is crucial for understanding the evolution of key structures in land plants. Moss sporophytes exhibit higher photosynthetic autonomy, which may be the key reason for their numerous stomata.
