Classification of living organisms
Characteristics :- MRS.GREN
-Movement :
The process by which the living organism move its body or part of it into a new
area and change position.
-Respiration :
The process in which the chemical reaction of breaking down of nutrients to
provide the energy needed for growth and tissue prepare.
-Sensation :
The process by which animal detect and sense the changes in their environment.
-Growth :
Malak Eslam Mohammed
The process by which increase in size and dry mass happens due to the increase of
cell size and number.
-Reproduction :
The process by which the living organisms produces new individuals of their own
kind.
-Excretion :
The process in which the living organisms get rid of the harmful substances and
wastes and exit them out of the body.
-Nutrition :
The process in which obtaining food to provide energy for growth and tissue
repair.
*Note : The process of gaining food in Animals is Ingestion , in Plants is
Photosynthesis.
, Series of classification
in the word " KPC,order,FGS "
1) Kingdom :
For example :
Animals and Plants
2) Phyllum :
For example :
Vertebrates and invertebrates
3) Class :
No examples
4) Order :
No examples
5) Family :
Malak Eslam Mohammed
No examples
6) Genus :
No examples
7) Species :
No examples
-Definition of species :
It is group of organisms which have a lot of similar features and can breed tighter
producing new offspring fertile individuals.
Importance of classification of living organisms :-
1. To facilitate their studies and identification of living organisms.
2. To find out their relation with human beings.
