Abstract: A method of determining and characterizing photosynthesis in plant parts of one or more plants includes capturing a plurality of images of the plant parts of the one or more plants with a sensor. Fluorescence of the plant parts of the one or more plants is measured such as by storing a sensor image of observed fluorescence. Light absorbed by the plant parts of the one or more plants is estimated such as by observing red and/or infrared reflectance of the plant parts. A characteristic of photosynthesis such as linear electron flow in plant parts of the one or more plants is derived using the measured fluorescence of the plant parts, the reflectance and the light absorbed by the plant parts, and/or the three-dimensional model comprising the plant parts of the one or more plants.
