Study Notes
Binomial Nomenclature
- Species are named using a binomial system
- The first part is the genus name (capitalized)
- The second part is the species name (lowercase)
- Example: Homo sapiens (modern humans)
Species Definition
- A species is a group of organisms
- They have similar morphology and physiology
- They can interbreed and produce fertile offspring
Taxonomy
- Taxonomy is a hierarchical system for classifying species
- Species are classified by characteristics
- From smallest (species) to largest (domain)
- Domains are larger than kingdoms
- Organisms in the same genus are more closely related than those in the same family.
Prokaryotes and Eukaryotes
- Bacteria and Archaea are prokaryotes
- Prokaryotes lack a nucleus
- Bacteria and Archaea cell membranes differ
- Eukaryotic cells have a double layer of phospholipids in their cell membranes
- Eukaryotes have nuclei
Classification based on rRNA
- Organisms are categorized based on rRNA types.
- Bacteria and Archaea are classified differently based on rRNA type
