Branches of Biology Basic Understanding of Science, Biology and it’s related branches  Definition of Science Science (from the Latin word scientia, meaning “knowledge ”) It is a systematic enterprise that builds and organi zes knowledge in the form of testable explanation s and predictions about the universe Or, science is an organized form of knowledge or systematic knowledge That is, knowledge through process  Biology The Word Biology is the combination of two Greek words (bios – life, logos – study) Biology is the branch of science which deals with the study of living objects and their life processes It covers all aspect of the study of living creatures like growth, structure, occurrence, classification, ecology, economics importance, external form, organization, internal structure, nutrition among others Cont’d Being broad – based and multidisplinary, the term biolo gy is often replaced by the term “life science or biologi cal science. ” The term biology was coined by Jean-Baptiste Lamarck Aristotle is know as the “Father of Biology ”  Now questions arises like: what is Life? What is living? How can you differentiate between Living and non-living since we define biology as t he science which deals with the study of living objects  Life is a set of characteristics which differe ntiate organisms from non-living objects These set of characteristics include reproducti on, growth, homeostasis, movement, nutriti on, respiration among others For a thing to be called a living thing, there must be a set of these  Botany Botany is the branch of biology which deals wit h the scientific study of different aspects of pla nts and plant-like organisms which include alga e, fungi, lichens, mosses, ferns, conifer, and flow ering plants The ancient Greek Theophrastus (371–286 B.C.E.) is known as the “Father/Founder of Botany”  Microbiology Microbiology is the branch of biology that deals wit h the scientific study of all living organisms that are too small to be visible to the naked eye. These organisms include: bacteria, archaea, viruses, f ungi, prions, protozoa, and algae, collectively known as ‘Microbes’ Antonie Philips van Leeuwenhoek is known as the “Father of Microbiology” Pure Branches of Biology The pure branch of biology include the following: 1. Morphology 8. Ecology 2. Anatomy 9. Embryology 3. Histology 10. Genetics 4. Cytology 11. Paleontolog y 5. Cell biology 12. Taxonomy 6. Molecular biology 13. Evolution 7. Physiology 14. Pathology  Morphology It is the study of external form, size, shape, color, external structure and relative position of living organisms Anatomy It is the study of internal structure which can be observed with unaided eye after dissection Physiology It is the study of different types of body functions and process es or the functional activities of a living organism  Cytology It is the study of form and structure as well as the function of cells including the behavior of nucleus and other organelles Histology It is the study of tissue organization and structure as observed through light microscope Embryology It is the study of fertilization, growth, division and different iation of the zygote into embryo or early development of living beings before the attainment of structure and size of the offspring  Taxonomy It is the science of identification, nomenclature and classification of organisms Genetics It is the study of inheritance of characters or heredity and variations. Heredity is the study of expression and transmission of traits from parents to offspring. Ecology It is the study of living organisms is relation to other organism and their environment  Evolution It studies the origin of life as well as new types of organism from the previous ones by modifications involving genetic changes and adaptations. Paleontology It deals with the study of fossils or remains and impressions of past organisms present in the rocks of different ages.  Cell Biology It is the study of morphological, organizational, biochemic al, physiological, genetic, developmental, pathological and evolutionary aspects of cell and its components. Molecular Biology It is the study of the nature, physicochemical organization, synthesis working and interaction of bio-molecules that br ing about and control various activities of the protoplasm Pathology Applied Branches of Biology The applied branch of biology is divided into two main streams: Applied Botany Applied Zoology  Applied Botany Some important branches of applied botany are; 1. Agriculture 1. Horticulture 1. Pharmacognosy 1. Forestry …  Applied Zoology Some important branches of applied zoology are; 1. Sericulture 2. Apiculture 3. Lac culture 4. Poultry 5. Pisciculture 6. Animal husbandry  Some different branches of science, biology specifically, has become very importance in this millennium With the above idea of the branches of biology, let us have some idea of the biological importance in other branches of science. A Acariology Study of ticks and mites Actinobiology The branch of science which deals with the study of radiation effects on organisms Aerobiology Study of flying organisms  Agroforestry This branch deals with forms of land used on which herbaceous crops and trees crops are cultivated Agronomy Science which deals with the crop plants Agrostology Study of grasses Anthology Study of flowers  Anthropology Study of apes and man Apiculture Study of Bee keeping Araneology Study of spiders Arthrology Study of joints B Bacteriology Study of bacteria Batrachology Study of frog Biochemistry Branch of science which deals with the study of chemical reactions in relations to life activities  Biometrics Statistical analysis of different results of biological experiments Biotechnology Us of biological organisms in commercial processes for producing fine chemicals such as drugs, vaccines and hormones etc..
