Question
The author had previously found that one of the advantages of leaf hairs in Encelia farinosa was reducing leaf temperatures such that photosynthetic rates or carbon gain rates were higher. Why would lower leaf temperatures result in higher photosynthetic rates?
lower leaf temperatures would cause lower leaf-to-air vapor pressure deficits, which would lower transpiration rates
lower leaf temperatures would be closer to the (relatively low) temperature optimum for photosynthesis in this species
a.lower leaf temperatures would cause lower leaf-to-air vapor pressure deficits, which would lower transpiration rates
b.lower leaf temperatures would be closer to the (relatively low) temperature optimum for photosynthesis in this species
Explanation / Answer
Lower leaf temperature would be closer to low temperature optimum for photosynthesis in species
