Study Notes
Plant and Animal Life
- Plants and animals are two major kingdoms of life.
- Plants are typically immobile, rely on photosynthesis for energy.
- Animals are typically mobile, require food for energy.
Plant Classification
- Plants are classified into herbs, shrubs, and trees.
Animal Classification
- Animals are classified by their habitat: land, air, and sea.
Carolus Linnaeus
- Carolus Linnaeus is a botanist who developed the modern system of classifying organisms in 1753.
Taxonomy
- Taxonomy is the science of classifying organisms.
- Taxonomy uses a hierarchical system to classify organisms.
Taxonomical Hierarchy
- The hierarchy consists of eight levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Domain Level
- Domain is based on the presence or absence of a nucleus and organelles in cells.
Kingdom Level
- Kingdom is based on the ability of organisms to move independently.
Phylum Level
- Phylum is based on the presence or absence of a backbone (spinal column).
Class Level
- Class is based on how offspring are fed, for instance, through glands.
Order Level
- Order is based on feeding habits, such as carnivore, herbivore, and omnivore.
Family Level
- Family is based on the physical structure and characteristics of organisms, including posture and brain structure.
Genus Level
- Genus is based on the shared characteristics of organisms within a group
Species Level
- Species is based on biological characteristics, such as DNA similarity and breeding habits.
Phylogeny
- Phylogeny studies the evolutionary history of organisms.
Cladistics
- Cladistics studies the relationships between organisms based on shared characteristics.
