    It discusses all of the parameters used in lake models by Kramer, Hendrickson, and Klughammer. In addition to these general purpose instruments, researchers often design or adapt other instruments tailored to the specific stress response they are studying.

    Current evidence indicates that reaction centers are connected with shared antennae in terrestrial plants. The model that represents the newer understanding of the antennae - reaction center relationship is called the lake model. Plant Physiology.

    1. As such, it can give a measure of the rate of linear electron transport and so indicates overall photosynthesis.

    2. In particular, recent advances in the area of laser-induced fluorescence LIF also provide an opportunity of developing sufficiently compact and efficient sensors for photophysiological status and biomass assessments.
