Study Notes
Linnaeus
- Carl Linnaeus, ennobled as Carl von Linné, was a Swedish botanist, physician, and zoologist.
- Known as the "father of modern taxonomy" for formalizing binomial nomenclature.
Fungi
- Group of eukaryotic organisms, including yeasts, molds, and mushrooms.
- Characterized by their role in decomposition and nutrient cycling.
Heterotrophs
- Organisms that obtain nutrition from complex organic substances.
- Include many animals, fungi, and some bacteria.
Photosynthetic
- Describes organisms that require sunlight to synthesize nutrients through photosynthesis.
- Key process for green plants and some bacteria, supporting life on Earth.
Monera
- A kingdom encompassing unicellular prokaryotic organisms, primarily bacteria.
- Established by Ernst Haeckel in 1866, marking a foundational step in microbial classification.
Archaebacteria
- Domain of single-celled prokaryotic microorganisms known as Archaea.
- Initially classified as bacteria; now recognized as a separate group due to significant genetic differences.
Protists
- Eukaryotic organisms that do not fit into the animal, plant, or fungus kingdoms.
- Lack a cohesive classification and include diverse forms of life, from unicellular to multicellular organisms.
Eukarya
- Domain containing organisms with cells that have a membrane-bound nucleus.
- Includes animals, plants, fungi, and protists.
Unicellular
- Organisms made up of a single cell.
- Examples include bacteria, archaea, and some protists.
Taxonomy
- Science focused on defining and naming biological groups based on shared characteristics.
- Facilitates understanding of relationships among organisms.
Phylum
- Principal taxonomic category ranking above class and below kingdom.
- Represents a major lineage of organisms sharing structural features.
Claudogram
- A branching diagram illustrating cladistic relationships among species.
- Highlights evolutionary connections based on shared derived traits.
Binomial
- A two-part naming system for species, consisting of genus and specific epithet.
- Essential for standardizing species identification across scientific fields.
Nomenclature
- System of assigning names or terms based on established rules in specific disciplines.
- Provides clarity and uniformity in scientific communication.
Phylogeny
- Branch of biology that studies the evolutionary development of species.
- Explores the ancestral relationships and diversification of organisms over time.
6 Kingdoms
- Classification includes: Plants, Animals, Protists, Fungi, Archaebacteria, and Eubacteria.
- Represents a comprehensive view of biological diversity.
Derived Characters
- Traits that evolved within a clade, distinguishing members from others.
- Important for understanding evolutionary relationships and classifications.
Traits
- Features or characteristics of an organism.
- Can be structural, behavioral, or physiological.
3 Domains
- Classification system includes Archaea, Bacteria, and Eukarya.
- Reflects key genetic and evolutionary distinctions among major life forms.
Multi-cellular
- Organisms composed of multiple cells, often showing specialization of function.
- Examples include plants, animals, and many fungi.
Eubacteria
- Large group of bacteria with simple cells and rigid cell walls.
- Includes "true" bacteria and cyanobacteria, differing from archaebacteria.
DNA Classification
- Classification based on genetic similarity, evolving from form-based classification.
- Provides a more accurate understanding of the relationships and evolution of species.
