AIM OF CLASSIFICATION The classification of organisms provides an advantage in the investigation and observation of living things.
Carl Von Linnaeus was the first person to classify living things in a scientific way in 1735. • He was use binomial nomenclature. Latin language is used in binomial nomenclature.
In binomial nomenclature, each organism has two names. • First of them is genus name, other is species name. • Pinusnigra (Black pine). • Pinus is name of genus and nigra is name of species.
SPECIES: It is group of organisms which members have many similarities.
Properties of species • 1-They must produce fertile offspring. • 2-They must have the same chromosome number. 3-The members of species must be able to mate.
HORSE DONKEY MULE Mule can’t reproduce. Because it isn’t a species.
A group of similar species is called genus. • Organisms which belong to same genus, have same genus name. Felisdomesticus (House cat) • Felistigris (Tiger) • Felisleo (lion)
Pinusnigra • Pinusbrutia • Pinushalapensis
A group of similar species is called genus. • A group of similar genera (sing:genus) is called family. A group of similar family is called order. A group of similar order is called class. A group of similar classes is called phylum(Phyla). A group of similar phylum is called kingdom.
From kingdom to species the following trends are observed • 1-The number of groups decreases. • 2-Similarities in organisms increases • 3-The number of members decreases
Kingdom : Animalia Phylum : Chordata Class : Mammalia Order : Primates Family : Hominidae Genus : Homo .Species : Homo sapiens
Some organisms like both animals and plants. Ex:Euglena Euglena likes animals because it can move. It also likes plants because it has chloroplast in its structure.
