About the framework
Applying Dichotomous Keys to Plant Classification
This template applies the dichotomous key framework to the plant kingdom — one of the most common biology lab activities from middle school through introductory botany courses. A dichotomous key works by presenting a series of binary choices (yes/no questions about observable characteristics), each of which narrows the identification until a single group remains.
The key progresses from the most fundamental division (vascular vs. non-vascular) through increasingly specific characteristics: spore vs. seed reproduction, naked seeds vs. enclosed seeds (gymnosperm vs. angiosperm), and parallel vs. netted leaf veins (monocot vs. dicot). This hierarchy mirrors actual taxonomic classification, so students learn both the identification process and the evolutionary relationships.
Customize for different classification targets: ask the AI to create a dichotomous key for local tree species, aquatic plants, or fungi. You can also add more endpoints — splitting monocots into grasses, lilies, and orchids, or splitting conifers into pines, spruces, and cedars.
What's included
What you get
- Decision tree with 4 diamond question nodes and 5 identification endpoints
- Questions: vascular tissue, seed production, seeds in fruit, leaf vein pattern
- Endpoints: moss, fern, conifer, monocot, dicot
- Yes/No labeled edges at every branching point
- Color-coded: orange decisions, green identifications

Frequently asked questions
Common questions
Can I add more plant species to the key?
Yes. Ask the AI to 'Add sub-branches splitting monocots into grasses, lilies, and orchids, and splitting dicots into roses, oaks, and sunflowers.' It will extend the decision tree with additional identification questions.
Can I create a dichotomous key for animals instead?
Absolutely. Ask the AI to 'Create a dichotomous key for classifying vertebrates into fish, amphibians, reptiles, birds, and mammals.' The decision tree structure works for any classification system.
How do I use this for a lab activity?
Export as PDF and have students follow the key with real plant specimens or images. They start at the first question and follow the Yes/No paths until they reach an identification. Ask the AI to 'Add a blank template version students fill in themselves.'
