Cannabis gas exchange, photosynthesis, transpiration, stomatal conductance, PPFD, temperature, and carbon-dioxide response under measured conditions.
Visual lesson 02
Photosynthesis
Connect light capture, carbon dioxide entry, water status, chloroplast function, carbohydrate production, leaf age, and light history while avoiding the assumption that one leaf gas-exchange measurement predicts whole-plant yield.
Interactive academic visual
Photosynthesis
Light energy, carbon dioxide and water support carbohydrate productionLight capture
Photosynthetic pigments absorb usable wavelengths of light and transfer energy into photochemical reactions.
