Classification for biodiversity

Topic 5.3

Essential idea: Species are named and classified using an internationally agreed system.

Understandings

5.3.U1 The skin and mucous membranes form a primary defense against pathogens that cause infectious disease

Binominal nomenclature using genus and species

5.3.U2 When species are discovered they are given scientific names using the binomial system

Naming a new species

5.3.U3 Taxonomists classify species using a hierarchy taxa

Explanation of classifying using taxa

5.3.U4 All organisms are classified into three domains

Classification using the three domains

5.3.U5 The principal taxa for classifying eukaryotes are kingdom, phylum, class, order, family, genus and species

Classification taxa used for eukaryotes

5.3.U6 In a natural classification, the genus and accompanying higher taxa consist of all the species that have evolved from one common ancestral species

Natural classification using genus and common ancestor

5.3.U7 Taxonomists sometimes reclassify groups of species when new evidence shows that a previous taxon contains species that have evolved from different ancestral species

5.3.U8 Natural classification help in identification of species and allow the prediction of characteristics shared within a group                   

Natural classification for predicting characteristics

Applications

5.3.A1 Classification of one plant and one animal species from domain to species level

Classification of one plant and one animal

5.3.A2 Recognition of features of bryophyta, filicinophyta, coniferophyta and angiospermophyta

Distinguish between the following phyla of plants

Observe the organisms for each phylum of plants and identify the simple external recognition features that allow for the identification of each phylum.

Placing your mouse pointer on the figures below will reveal the external features.

Features of Bryophyta
Features of Filicinophyta
Features of Coniferophyta plants
Features of Angiospermophyta plants

5.3.A3 Recognition of features of porifera, cnidaria, platyhelmintha, annelidia, mollusca, arthropoda and chordata

Distinguish between the following phyla of animals

Observe the organisms for each phylum of animals and identify the simple external recognition features that allow for the identification of each phylum.

Placing your mouse pointer on the figures below will reveal the external features.
