Biology GCSE - Topic 1, classification

Classification is the process by which living organisms are categorized and grouped according to their characteristics, habitats and evolutionary adaptations and origins. 

The binomial naming system is the system which gives all organisms a scientific name. It allows scientists to:

• Conserve species- e.g. it's easy to presume that two similar looking species are the same, when they are actually different. 
• Study species- Scientists can share information on the species by identifying and naming them
• Target conservation efforts- successfully protect areas that have a great variety of different species
• Communicate worldwide/identify species- it can be confusing when species have different names for different languages

The binomial naming system:

 Kingdom, Phylum, Class, Order, Family, Genus, Species

You can easily remember this with a simple sentence like this one:

King, Phil, Called, Oliver, For, Green, Soup

1. KINGDOMS

Plantae- chlorophyll, nucleus, multicellular, autotrophs, call walls e.g. trees

Animalia- no chloropyll, nucleus, multicellular, heterotrophs, no cell walls e.g. humans

Fungi- saprophytes, cell walls, no chlorophyll, multicellular e.g. mushrooms

Protoctista- unicellular, nucleus e.g. algae

Prokaryotes- unicellular, no nuclues e.g. bacteria

2. PHYLUM
