Penguins can't fly in the air like most birds, instead they use their wings like flippers to move through the water
Biological classification
A system scientists use to sort all living things into groups based on their similarities
Classifying organisms
1. Describe what biological classification is
2. Classify organisms based on their characteristics
3. Explain the importance of classifying living things
Biological classification helps us understand how living things are related to each other, makes studying and discussing the variety of life on Earth easier, and helps scientists quickly identify and categorise new species
Binomial (two-part) namingsystem
Each living thing has a name consisting of two Latin words: the genus and the species name
Carl Linnaeus' system
Consists of a hierarchy of groups, from broad to more specific ones: Kingdom, Phylum, Class, Order, Family, Genus, Species
Human classification
Animalia
Chordata
Mammalia
Primate
Hominidae
Homo
sapiens
Plant kingdom
Most organisms can make their own food using sunlight, includes conifers, mosses, ferns and flowering plants
Animal kingdom
Most organisms can move around and eat other organisms for energy, have specialised tissues and muscles used to perform complex functions
Monera kingdom
Single-celled organisms with no defined nucleus, many found in extreme environments
Fungi kingdom
Organisms get their food by breaking down matter around them, cell walls made of chitin
Protista kingdom
Organisms that are neither plants, animals nor fungi, challenging to categorise since they have few things in common
