classification revision

Classification test - week 4

By Benjamin Graham

​• explain that classification systems were developed to help scientists communicate information about organisms despite their different locations and languages • describe some of the changes in classification systems that have been used since Aristotle in 322BC • identify the current classification system as that devised by Linnaeus in the 1700s. • describe the eight characteristics shared by all living things using the acronym MR N GREWW. • explain that different keys are used to sort organisms into groups. The dichotomous key sorts organisms by making simple ‘yes’ or ‘no’ decisions. • construct and read keys in tabular and diagram form • describe the two-part naming system devised by Carl Linnaeus • identify the genus and species of an organism from its two-part name. • explain that Life on Earth is classified by scientists into 5 kingdoms: Animalia (animals), Plantae (plants), Fungi, Protista (algae) and Monera (bacteria) • understand that classification is based on cell structure, what the organisms look like and how they absorb nutrients. • explain that invertebrates have either an exoskeleton or no skeleton • explain that invertebrates make up 96% of all animals • identify the six main phyla of invertebrates: arthropods, poriferans, molluscs, cnidarians, nematodes/platyhelminths/annelids and echinoderms. explain the difference between a vertebrate and an invertebrate • explain that vertebrates are sorted into five Classes – mammals, fish, birds, reptiles and amphibians • use the terms endotherm and ectotherm to group the vertebrates.

​Remember MR N GREWW

​Classification helps us organize and understand the vast amount of information in the world by grouping things based on shared characteristics. This makes it easier to study, compare, and communicate about those things, whether they are objects, ideas, or living organisms
