Features Of Organisms
Overview
Once organisms are classified, the next question is: which features place an organism in one group rather than another? A few key features are enough to sort any living thing into a kingdom, and within the animal kingdom into vertebrate classes or arthropod groups.
In this lesson you will learn the diagnostic features of plants and animals, the five vertebrate classes, the four arthropod groups and, at Extended level, the five kingdoms, the main plant groups and the odd case of viruses. By the end you will be able to classify an unfamiliar organism from its features alone.
Objectives
- State the main features used to place animals and plants into the appropriate kingdoms
- State the main features used to place organisms into groups within the animal kingdom, limited to: (a) the main groups of vertebrates: mammals, birds, reptiles, amphibians, fish (b) t he main groups of arthropods: myriapods, insects, arachnids, crustaceans
- Classify organisms using the features identified in
- [Supplement] State the main features used to place all organisms into one of the five kingdoms: animal, plant, fungus, prokaryote, protoctist
- [Supplement] State the main features used to place organisms into groups within the plant kingdom, limited to ferns and flowering plants (dicotyledons and monocotyledons)
- [Supplement] Classify organisms using the features identified in
- [Supplement] State the features of viruses, limited to a protein coat and genetic material
