Introduction to Biology Flashcards
What is science?
The word science is derived from the Latin word scientia, meaning knowledge.
In ancient times, science meant knowledge or learning.
Nowadays, science is the study of the physical and natural world around us
Define Biology.
The word biology consists of two Greek words bios meaning life and logos meaning thought, reasoning, or study.
Biology is the study of living things.
It helps us to understand how living things relate to one another and to their surroundings.
Botany?
Botany is the study of plants.
Zoology

Microbiology?
the scientific study of microorganisms, those being unicellular, multicellular, or acellular.
Morphology
the study of the size, shape, or in other words, the external structure of the organism.
Anatomy?
study of the internal structure of organisms.
What anatomy is also called?
internal morphology
Physiology?
study of the functions and mechanism of various organs of the organisms
Histology?
microscopic study of tissues of organisms.
cell biology?
study of the structure and functions of the cell.
genetics?
study of genes and heredity.
Embryology?
study of the developmental stages of an organism from egg to the formation of a new organism. It deals with the developmental stages of embryo and congenital disorders that occur before birth.
Taxonomy
Taxonomy is the practice and science of categorization or classification.
classification and naming of an organism
Ecology is also called
environmental biology
ecology?
study of the interrelationship of organisms and their environment. An ecologist studies the relationship between living things and their habitats
socio-biology
the study of the social behavior of organisms that makes societies
immunology
the ability of the body to protect itself from foreign substances and cells including infectious microbes and pathogens is called immunity and the study of immunity is called immunology.
what are the divisions of biology?

what are fossils?
Fossils are the remains of living things preserved by natural processes.
why is the study of fossils important?
The study of fossils helps us to understand
where life and humans came from
how our Earth and environment have changed through geological time
process of evolution.
Pharmacology?
The science that deals with the study of drugs and their effects on the systems of the human body.
what are parasites?
Parasites derive their nutrients & shelter from the host organism and in return cause harm to the host organism.
Palaeontology
study of fossils
Biophysics?
The study of biological phenomena according to the principles & laws of Physics.
Biological organisms work on the principles of physics eg the movement of muscles & bones.
what are the careers that require a background in Biology?
7 careers
MBBS
Fisheries
Farming and Agriculture
Animal Husbandry
Biotechnology
Horticulture
Forestry
MBBS full form?
Bachelor of Medicine & Bachelor of Surgery
what is medicine?
Medicine is the diagnosis and treatment of different diseases
what is surgery?
Surgery is the branch that treats diseases by removal or replacement of defective parts or organs.
Biometry
Statistics is related to collecting and analyzing various data or facts. The collection of biological data through observations, experiments and analysing them according to statistical rules for biological study
biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. It is the discipline combining the study of chemistry with the study of biology, or in other words a sub-discipline of both chemistry and biology. Living organisms consist of carbon, hydrogen, oxygen, nitrogen, etc and chemical reactions such as digestion of food, respiration and photosynthesis take place in the organism.
biogeography?
The study of the distribution of plants and animals in different geographical regions of the world is called biogeography
Bioeconomics
The study of biology from an economic point of view. Production of wheat, fish rice and studying their export value etc are examples of bioeconomics. For example
the cost value and profit value of the
yield of wheat can be calculated through
bioeconomics and benefits or losses can be
determined.
Fisheries?
The fisheries sector makes a significant contribution to the economy of Pakistan. Careers associated with it are fish farming, fishery management, and related research.
Fisheries is the professional study of fish production. There are departments in Pakistan where professional of fisheries are employed. They serve for enhancing the quality and quantity of fish production. In Pakistan this profession can be adopted after the bachelor or masters level study of zoology and fisheries.
Animal Husbandry?
Animal Husbandry is the care and breeding of DOMESTIC animals. The careers associated are veterinary science, animal breeding and animal training etc
