Transcript of Power point presentation on topic Classification -Arunima V.S
Grouping of different types of organisms based on similarities
Branch of biology that deals with classification of living things
Carl Linnaeus classified the living world as plant kingdom and animal kingdom
Carl Linnaeus suggested different levels of classification on the basis of similarities and differences and devised the system of naming each organism scientifically .
Hence he is considered the father of scientific classification
PLANT KINGDOM ANIMAL KINGDOM
All plants are included in the Kingdom Plantae
Plants vary greatly in form and size. The body is usually asymmetrical. In higher forms of plants structures like leaves and plants have a definite form and shape
Multicellular organisms which do not have the power the locomotion
Nutrition in plants is usually autotrophic.
The body of the plant is composed of cells. All the cells of the plant body have a distinct cell wall and nucleus
Plants have reserve food as starch
Plants grow throughout their life span
All animals are included in this kingdom
Body of animals exhibits a definite symmetry , form and shape.
Animals can move from one place to another.
Animal body is also made up of cells, the cells, the cells do not have the cell wall.
Animals cannot prepare food by themselves hence they are heterotrophic
Carl Linnaeus[1700’s]
All organisms are divided into seven levels of classification
These are the seven levels in the classification of plants and animals
Each kingdom is classified in to many phylum's and each phylum is classified in to many classes
In Animal kingdom each class is divided in to many series
But in plant kingdom each class is divided in to many series
The order of each animal kingdom series of each plant kingdom is divided in to many families
Each family is divided in to many Genus and each genus is divided in to many species
The basic unit of classification is species.
One kind of organisms that can mate with each other and produce fertile offspring.
The members of organisms of two different species cannot interbreed.
The off spring produced in interspecific breeding may be fertile.
Eg; tiger-a species named tigris
Closely related species are united to
form genus
EG:- Panthera [ lion , tiger , cheetah ]
Group of similar genera constitute a family
EG:- Felidae [ cheetah ,lion , tiger ]
Similar families are grouped into order
Eg:- Carnivore [ flesh eating animals in mammalian]
Similar orders are grouped in to
class
Eg:-Mammalia [ those who give birth to young ones and feed them with milk ]
Similar classes are grouped under next category called phylum
Eg:- chordata [ animals having vertebral column ]
Kingdom represents the highest category in which all similar phyla are grouped in to order
EG : - Animalia , plantae
Living organism are numerous and highly diversified in their character.
These organisms are classified into different groups for better approach and understanding
Carolus Linnaeus classified the living organism in systematic manner.
This kingdom of classification laid the base for modern classification and was quite a reasonable at that period of time ,plants and animals could be quite easily distinguished.
