Cannabis sativa mature-leaf macro- and microscopic anatomy, including epidermis, palisade and spongy mesophyll, midrib support tissues, vascular bundles, trichomes, and cystolith-bearing structures; used for structural anatomy rather than universal physiological thresholds.
Visual lesson 01
Healthy leaf baseline
Use leaflet shape, venation, petiole, surface condition, color distribution, posture, developmental stage, and cultivar context as the reference before judging abnormality.
