Cannabis sativa stem morphology and cross-sectional anatomy, including peripheral bast fiber bundles, xylem-rich inner tissues, lignification gradients, internode traits, and genotype-dependent structural variation.
Visual lesson 08
Bast fibers & structural support
Locate cellulose-rich bast fiber bundles toward the stem periphery and the more lignified xylem-rich inner core, then connect tissue position, maturation, and cell-wall composition to mechanical support.
Primary visual specification
Cannabis stem support-tissue cutaway with bast fiber and xylem callouts
Create an academically accurate cannabis stem support-tissue cutaway with bast fiber and xylem callouts for the Bast fibers & structural support 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.
