Study Notes
Organism Classification
- Archaea and Eukarya lack peptidoglycan in their cell walls.
- Carl Woese devised a classification system based on cellular organization in 1978.
Prokaryotic Kingdom
- The Kingdom Monera contains all prokaryotic organisms.
Characteristics of Protists
- Protists differ from other kingdoms due to their mostly unicellular organization and diverse forms.
- Protists possess eukaryotic cells, which have a true nucleus.
Bacterial Cell Wall
- Bacteria have a characteristic protein-carbohydrate complex known as peptidoglycan in their cell walls.
Domains of Life
- Viruses are NOT classified as a domain of life.
Scientific Nomenclature
- Scientific names assign a unique, standard identification to each organism, aiding in classification.
Bacterial Naming
- In Staphylococcus aureus, 'aureus' indicates the organism's characteristic gold color.
Etymology of Scientific Names
- Scientific names are Latinized to ensure universal understanding and consistency among scientists.
Specific Epithet Meaning
- The specific epithet 'coli' in Escherichia coli indicates association with the colon.
Nutritional Characteristics
- Kingdom Plantae includes organisms that predominantly engage in photoautotrophic nutrition.
- Kingdom Animalia comprises organisms that primarily have heterotrophic nutrition.
- Kingdom Fungi primarily utilizes decomposing organic material for nutrition.
Evolutionary Role
- Domain Eukarya contains organisms that are essential to the evolution of life on Earth.
Common Traits Across Kingdoms
- Organisms in Kingdom Animalia share the common characteristic of being multicellular and heterotrophic.
- Most microorganisms, including algae and protozoa, exhibit unicellularity, foundational to their classification.
