Life science is one of the major branches of science. It
comprises of fields of science that involve the scientific study of living
organism and human beings. Life science is vital in improving the quality and
standard of life.
Life science has a lot of topics of study but the major
include the following:
- Anatomy
- Botany
- Cell biology
- Microbiology
- Ecology
- Immunology
- Pathology
- Pharmacology
Anatomy
This is the scientific study of parts of animals. Anatomy
can be divided into two categories: macroscopic anatomy and microscopic
anatomy. Macroscopic anatomy is the study of structures that can be seen by
unaided vision with the naked eye, when suitably presented or dissected.
Microscopic anatomy is the study of structures that cannot be viewed with the
naked eye. One has to use a microscope in order to view the structures
Botany
Also referred to as plant science. It is the scientific
study of plants and plant life. Botany encompasses study the growth, replica,
metabolism, diseases and evolution of plants.
Cell biology
Cell biology is also referred to as cytology. It is the
scientific study of the cell. This study involves the study of the
physiological properties, structure, organelles,relationships, life cycle,
division and death of cells. Cell biology covers both single celled and
multicellular organisms.
Microbiology
Microbiology
It is the scientific study of microscopic organisms, single
celled(unicellular), multicellular or acellular(lacking cells). Microbiology is
divided into two major divisions: pure and applied microbiology.
Ecology
It is a branch of life science that studies the relationship
among organisms and their environment. Topics that ecologists tend to explore
under ecology include of the diversity, distribution, biomass, population of
organisms and competition between organisms within and among ecosystems. Mostly
ecologists seek to expound on life processes, interactions and variations, the
movement of materials and energy through living communities, the development of
ecosystems and additionally the amount and distribution of organisms.
Immunology
It is a branch of biomedical science that covers the study
of all aspects of the immune system in all organisms. Immunology deals with the
defence mechanisms of the organism that help an organism to fight its
susceptibility to foreign organisms.
Pathology
This is the scientific study and diagnosis of diseases in
organism, through examination of tissues, organs, body fluids and the whole
body. Pathology is divided into major nine divisions which consist of:
anatomical, chemical, clinical, forensic, genetic, general, hematology,
immunopathology and microbiology.
Pharmacology
This is the scientific study of the actions of the drug in
an organism. Pharmacology tends to expound more on the drug composition and
properties, synthesis and drug design. This field is divided into two major
categories: pharmacodynamics and pharmacokinetics.
