Classification of Organisms Chapter 14

Basic Biological Organization Atoms are organized into molecules Atoms are organized into molecules Cells are organized in tissues, Cells are organized in tissues, organs, organs, organ systems, organ systems, individuals, individuals, populations, populations, communities communities ecosystems biomes biosphere ecosystems biomes biosphere

How we classify organisms Biologists classify organisms into groups with similar characteristics to understand the diversity of life Biologists classify organisms into groups with similar characteristics to understand the diversity of life Classification of organisms = “taxonomy” Classification of organisms = “taxonomy” The system progresses from the most general to the most specific The system progresses from the most general to the most specific

The three domains of life are The three domains of life are Three Domains of Life 1. Bacteria 2. Archaea 3. Eukarya Figure Domain BacteriaDomain Archaea Domain Eukarya Kingdom ProtistaKingdom Plantae Kingdom Fungi Kingdom Animalia

DOMAINS Bacteria and Archaea are both prokaryotic domains * Domain Bacteria Domain Archaea Common bacteria Bacteria that live in extreme environments, like high temperatures.

Domain Eukarya is eukaryotic and includes four kingdoms: Domain Eukarya is eukaryotic and includes four kingdoms: 1. Protista 2. Plantae 3. Fungae 4. Animalia Figure Domain Eukarya Kingdom ProtistaKingdom Plantae Kingdom Fungae Kingdom Animalia

The Kingdoms For our purposes we will discuss Four Kingdoms, which are all part of Domain Eukarya: For our purposes we will discuss Four Kingdoms, which are all part of Domain Eukarya: Protista = unicellular eukaryotes Protista = unicellular eukaryotes Plantae = plants Plantae = plants Fungi = mushrooms, slime molds, fungi Fungi = mushrooms, slime molds, fungi Animalia = animals and mammals Animalia = animals and mammals

Plantae are photosynthetic. Ecologically they are producers. * Figure Domain Eukarya Kingdom Protista Kingdom Plantae Protista are single cell organisms. Domain Eukarya are Eukaryotes.

Fungae are decomposers that digest food outside of their cells before bringing food inside. Fungae are decomposers that digest food outside of their cells before bringing food inside. Animalia ingest organic food to digest internally. * Figure Domain Eukarya Kingdom Fungae Kingdom Animalia
