Genus
In biological classification, a genus is a rank used in the biological classification of living and fossil organisms. It is a level below family and above species. The genus name is always italicized or underlined.
Characteristics of Genus
- Grouping: A genus comprises one or more species that are closely related and share common characteristics.
- First Part of Scientific Name: The genus is the first part of the scientific name used to uniquely identify a particular organism. For example, in the scientific name Rosa canina, Rosa is the genus.
- Higher Taxonomic Hierarchy: Genus is an important level in the hierarchical classification of organisms, providing a way to group similar species together.

Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
