Cannabis leaf gas exchange under varying PPFD, temperature, and CO2; supports coupled response teaching while keeping experimental genotype and chamber conditions explicit.
Visual lesson 07
CO2 diffusion & photosynthetic response
Trace carbon dioxide from bulk air through the leaf boundary layer and stomata to photosynthetic tissues, then compare Cannabis responses to changing CO2 while keeping cultivar, PPFD, temperature, nutrient, and measurement conditions visible.
Primary visual specification
CO2 diffusion pathway and photosynthetic-response overlay
Create an academically accurate co2 diffusion pathway and photosynthetic-response overlay for the CO2 diffusion & photosynthetic response lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.
