Separate root from stem
Roots typically lack nodes and leaves and are positively gravitropic; stems bear nodes, leaves and buds and are generally positively phototropic. Floral diagrams show whorl arrangement, while floral formulas compress key characters.
OlympIQ exam lens
- ✓Stem: nodes, leaves/buds; root: root cap and root hairs.
- ✓Floral diagram shows spatial arrangement; formula summarises characters.
OlympIQ trap
Use several plant-body traits together rather than treating phototropism as the only distinction.
