Cannabis glandular trichome morphology, capitate-stalked and sessile forms, secretory disk cells, subcuticular storage, distribution, and specialized-metabolite biology.
Visual lesson 04
Clear, cloudy & amber
Use apparent optical condition as one observation among several, recognizing that lighting, focus, sampled tissue, gland integrity, developmental state, and genotype can affect interpretation and that appearance is not a direct cannabinoid assay.
Interactive academic visual
Clear, cloudy & amber
Optical appearance changes with gland development, sampling and imaging conditionsClear-appearing
Some gland heads appear more transparent when viewed under consistent lighting and focus, particularly earlier in development.

PracticeCan you explain what the visual is showing?
Why should apparent clear, cloudy, or amber trichomes be interpreted cautiously?
