# SMI3: Microbial Structural Components

Obtain, evaluate, and communicate information to examine the structural components of prokaryotic and eukaryotic microorganisms and their functions.

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

## Expectations

- **SMI3.a**: Use models to investigate and compare structural properties of prokaryotic and eukaryotic membranes and the functions associated with these membranes.
- **SMI3.b**: Construct an argument based on evidence on how prokaryotic cell walls differ from eukaryotic cell walls, and how these differences contribute to their function.
- **SMI3.c**: Develop and use models to demonstrate how internal organization differs between prokaryotes and eukaryotes and explain the functions of internal structures.
- **SMI3.d**: Construct an explanation of the endosymbiotic theory and its evolutionary relevance.
