THC Academy course
Leaves, Photosynthesis & Gas Exchange
Use healthy leaves as a baseline, then connect photosynthesis, stomata, transpiration, symptom language, and inspection workflow.
Course outcomes
What you should be able to do
- Use a healthy leaf as a structural and visual baseline.
- Connect photosynthesis to light, carbon dioxide, water status, and chloroplast function.
- Relate stomata and transpiration to temperature, humidity, airflow, and root-water supply.
- Describe leaf symptoms precisely before attempting diagnosis.
