# SBO2: Plant Phylogeny and Taxonomy

Obtain, evaluate, and communicate information to delineate the plant divisions based on current plant phylogenetic and taxonomic principles.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SBO2.a**: Construct an explanation based on evidence to compare nonvascular to vascular plants and seedless to seed plants.
- **SBO2.b**: Construct an argument based on evidence from traditional methods and emerging technologies (i.e., using physical characteristics and molecular evidences) to classify plants into major plant divisions.
- **SBO2.c**: Analyze and interpret data to develop models (i.e., cladograms and phylogenetic trees) based on patterns of common ancestry or convergence.

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.
