Study Notes
Characteristics of Living Organisms
- One characteristic shared by all living things is the ability to grow and develop.
- Growth involves a permanent increase in size and mass in living organisms.
Nutrition and Energy
- Organisms that make their own food using energy from sunlight are called autotrophs.
- Organisms that cannot make their own food and consume others instead are called heterotrophs.
Reproduction
- The characteristic that involves the process of making more of the same kind of organism is called reproduction.
Cell Structure
- Organisms made up of more than one cell are called multicellular organisms.
Classification of Living Organisms
- The process of grouping living things based on their similarities is called taxonomy.
- Taxonomists consider fossils and comparative anatomy to reveal the evolutionary relationships of organisms.
- Biologists classify organisms into different categories based on their shared characteristics.
- The science of naming, identifying, and classifying organisms is known as taxonomy.
- The internal and external structures of living organisms influence their classification.
History of Taxonomy
- Carl Linnaeus is known as the father of taxonomy.
- The three domains into which biologists divide the diversity of life are Archaea, Bacteria, and Eukarya.
- In the Linnaean classification system, the phylum is ranked immediately below the kingdom.
- The Greek philosopher Aristotle developed the first widely accepted biological classification systems.
- The term for the process of arranging various organisms into successive levels of biological classification is taxonomy.
