Biodiversity

Biodiversity

Refers to all the variety of life found on Earth, including plants, animals, fungi, and microorganisms, as well as the communities and habitats they form.

Genetic Diversity

Diversity of genes within a species.

Species Diversity

Diversity among species in an ecosystem.

Ecosystem Diversity

Diversity of habitats in a given unit area.

6 Kingdom System

Classification system including Eukaryotes (Plantae, Animalia, Fungi, Protista) and Prokaryotes (Eubacteria, Archaebacteria).

Biological System of Classification

Hierarchical classification system including Kingdom, Phylum, Class, Order, Family, Genus, and Species.

Carl Linnaeus

Developed the system of classifying living things, binomial nomenclature, and the 7-level classification system.

Binomial Nomenclature

Naming system developed by Linnaeus consisting of two Latin words for the genus and species name.

Dichotomous Key

Tool with paired statements used for classification based on shared observable characteristics.

Kingdom Archaea

Microscopic, prokaryotic cells without peptidoglycan, capable of surviving in extreme environments.

Kingdom Bacteria

Microscopic, prokaryotic cells with peptidoglycan, often pathogenic, reproduces through binary fission.

Kingdom Protista

Unicellular/multicellular eukaryotic organisms with cellulose cell walls, includes protozoans, algae, and slime molds.

Kingdom Fungi

Unicellular/multicellular eukaryotic organisms with mycelium bodies, heterotrophic, reproduces sexually/asexually.

Kingdom Plantae

Multicellular autotrophic organisms with cellulose cell walls, vascular/non-vascular, includes angiosperms and gymnosperms.

Angiosperms

Flowering plants with enclosed seeds, pollinated by animals/wind/water, examples include apple, dandelion, and rose.

Gymnosperms

Non-flowering plants with naked seeds, mainly wind-pollinated, examples include pine, spruce, and yew.

Kingdom Animalia

Multicellular heterotrophic organisms with eukaryotic cells, reproduces sexually, includes vertebrates and invertebrates, consists of 9 phyla.

Eukaryota

chromists, plants, alveolates, animals, fungi, rhodophytes, flagellates, basal protists

bacteria

cyanobacteria, heterotopic bacteria

archaea

halophiles, thermophiles
