claim: Plant stomata show higher and more variable CO2 levels
evidences.evidence_id: Photosynthesis:248
evidences.article: Photosynthesis
evidences.evidence: Plant species with the greatest photosynthetic rates and Kranz anatomy showed no apparent photorespiration, very low CO2 compensation point, high optimum temperature, high stomatal resistances and lower mesophyll resistances for gas diffusion and rates never saturated at full sun light.
