what is biology? branches of biology various aspects of life - Medlepius

                                                               BIOLOGY
The word biology itself is composed up of two Greek words that are
  • bios that means life
  • logos that means study                                                      

If generally you want to describe biology that you can state it as study of life but if you want to describe the scientific definition of biology than you can state it as scientific study of living organism 
in biology we deals with life or living organisms but along with the study of living organisms or life we also observe or study the non living environmental factors around living organisms that affect them in some way
                             


Branches of Biology
Biology itself is very diverse and vast so to organize things and to avoid any sort of confusion or to study different thing in a different manner we have divided biology into many fields or branches and each field/branch deals with different aspect of biology and some of the fields or branches of biology are as following

MORPHOLOGY
                                  morphology ( morph means form and logy means study ) is the branch of biology that deals with the study of form and structure of a living organisms it can be of two types
  • external morphology ( that deals with external form and structure of a organism  )
  • internal morphology also known as anatomy ( it deals with internal form and features of a living organism )

PHYSIOLOGY
                             physiology is the branch of biology that deals with the scientific study and mechanism of different processes occurring in living organisms this branch mainly focus on how living organism organs organ system tissues cells organelles bio-molecules carry out chemical and physical function that are occurring in a living organism and that are essential to maintain life of a living organism

HISTOLOGY
                        histology is the branch of biology that deals with the study of  microscopic anatomy of biological tissues

PALEONTOLOGY
                               paleontology is the branch of biology that deals with the study of fossil and the remains of dead or extinct animal fossils are either the actual remain or traces of an organism that lived in ancient times fossils may be found in resins ice or sand

GENETICS
                    genetics is the branch of biology that deals with the study of genes genetic variations and inheritance caused by genes

 MICROBIOLOGY
                              microbiology the branch of biology that deals with the study of microorganisms such as the bacteria virus protozoa and microscopic algae and fungi this field of biology basically includes fundamental research on biochemistry physiology cell biology ecology

MOLECULAR BIOLOGY
                                               the branch of biology that deals with the study of molecular basis of  biological activity between bio-molecules in the various system of a cell of a living organism

ENVIRONMENTAL BIOLOGY 
                                                       environmental biology or ecology the branch of biology that deals with the study of  relationship of an organism with its environment such as relationship of an organism with the organic and inorganic factors of its environment a it is related to human activities

MARINE BIOLOGY
                                 marine biology is the branch of biology that deals with the study of marine bodies such as seas and oceans and the the chemical and physical parameter that effect the live of organisms living in these bodies

FRESHWATER BIOLOGY
                                           freshwater biology is the branch of biology that deals with the study of rivers lakes and ponds and the physical and chemical parameters that effect the life of organisms in these bodies 

PARASITOLOGY
                        parasitology is the branch of biology that deals with the study of parasites their relationship with the host modes of nutrition mode of transmission life histories

HUMAN BIOLOGY 
                             human biology the branch of biology that deals with the study of humans  their genetics their anatomy function of different part parts of body their molecular biology

BIOTECHNOLOGY 
                                biotechnology is the branch of biology that deals with the study of welfare of making by using different organism
                         
BIOCHEMISTRY 
                  biochemistry is the branch of biology that deals with the study of chemical components and the chemical processes occurring in a living organism a basic knowledge of biochemistry is essential to understand the anatomy and physiology because all the structure of an organism have have biochemical organization

CELL BIOLOGY 
                   cell biology is the branch of biology that deals with the study of structure and function of the cell this fields mainly deals and describe cells as the structural and the functional unit of all living organisms

BOTANY  
                 botany is the branch of biology that deals with the study of plants their varieties its deals with ways to increase and boasts the yield and growth of the plant sand also to produces plants that are resistant to diereses

ZOOLOGY 
             zoology is defines as the branch of biology that deals with the study of animals this field includes biochemistry anatomy physiology environmental relations of animals this field also focus on producing yield of animals and to drive using things by using animals

BIO-GEOGRAPHY
                         bio-geography is defines as the branch of biology that deals with the geographical distribution of life on this planet earth

BIO-ENGINEERING
                   bio-engineering deals with the study production recombinant DNA it is such a DNA which is made up of two or more sources

                                                                       LIFE
There is no definite and final definite definition of life because there are such a lot of aspects of life that they are very difficult to be covered but we can differentiate living organisms from non living things but the helps of some of the charters given below that are shown by the living organisms but not by the non living things

  • all of the living organisms are highly complex entities 
  • all of the living organisms contains genetic programs of all their characteristics that were inherited from there parent to them 
  • all of the organisms can produce its own energy an use It for its body functions
  • all living organisms can carry out and control numerous chemical reactions to maintain their life 
  • all of the organisms show growth 
  • all living organisms protect their internal environment from the harms of the fluctuations of the external environment 
  • all living organisms cab produce organisms similar to themselves 
  • all living organisms respond to the changes of their surroundings
