Fossil ginkgo: stomatal indices high
late Permian period (275–290), Pleistocene (1–8) - low atmospheric carbon dioxide & ice age, low Cretaceous (146).
- Carotenoids
made in in chromoplasts.
- G3P: glyceraldehyde-3-phosphate -> glucose and other carbohydrates.
- Sugar cane:
fibrous stalks, sap rich in sucrose, convert 2% of solar energy to biomass. Need 6 m moisture.
