Lesson 17: Classification of Living Organisms Flashcards
Traditionally, how have living things been classified?
- Traditionally, living things have been classified into groups depending on their structure and characteristics.
Who was the classification system developed by?
- Classification system developed by Carl Linneaus.
How are organisms named?
- Organisms are named by the binomial system (developed by Carl Linneaus) of genus and species.
What different groups did Carl Linneaus classify living things into?
King Prawn Curry or Fat Greasy Sausages (HINT HINT)
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species.
Why did evidence of internal structures of organisms become more developed over time?
2 main reasons
- Improvements in microscopes
- Understanding of biochemical processes progressed.
What happened as a result of evidence of internal structures of living organisms becoming more developed?
- New models (different from Carl Linneau’s model) were proposed.
What led to the devlopment of the three-domain system?
- Evidence from chemical analysis.
Who was the three-domain system devloped by?
- Three- domain system devloped by Carl Woese.
What are the three domains?
1.) Arachea
2.) Bacteria (true bacteria)
3.) Eukaryotes
What are archea?
- Archae are primitive bacteria, usually living in extreme environments.
What organisms are included in the “eukaryotes” division in the three domains?
4 organisms included!!
1.) Protists
2.) Fungi
3.) Plants
4.) Animals
What are evolutionary trees?
- Evolutionary trees are a method used by scientists to show how they believe organisms are related.
How are evolutionary trees made (for both extinct and living organisms?)
- They use CURRENT CLASSIFICATION data for living organisms.
- They use FOSSIL DATA for extinct organisms.
