Cannabis sativa ploidy-associated differences in fan-leaf morphology, abaxial stomatal size and density, and related phenotype measurements; useful for showing that stomatal traits vary with genotype/ploidy rather than defining a universal species value.
Visual lesson 10
Stomatal traits & sampling context
Compare stomatal size, density, surface location, and gas-exchange measurements as traits that depend on genotype, ploidy, development, environment, and sampling method, avoiding a single species-wide numeric reference where the evidence does not support one.
Primary visual specification
Cannabis stomatal sampling and trait-comparison microscope plate
Create an academically accurate cannabis stomatal sampling and trait-comparison microscope plate for the Stomatal traits & sampling context 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.

PracticeCan you explain what the visual is showing?
Why should a stomatal density value measured on one Cannabis sample not automatically be used as a species-wide reference?
