In plants, respiration is usually inhibited in the light compared to the dark. Measuring respiration in the light is particularly difficult, because photosynthesis and photorespiration are occurring as well...
Why did Gingko almost disappear during the Triassic–Jurassic mass extinction when ferns did so well? The answer has relevance for future atmospheric changes.
There are several answers to this question. I expect all of you to say guard cells. Those of you who’ve read the previous item about chlorophagy might also be tempted to say plant vacuoles – presumably of guard cells...
Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. Šigut et al. find that this is indeed the case for broadleaved Fagus...
Sandalio and Romero-Puertas review the metabolism of reactive oxygen and nitrogen species (ROS and RNS) in peroxisomes and their contribution to the regulation of plant development and acclimation to stress conditions.
