Cell biology

Cell biology (also called cellular biology or cytology ) is an academic discipline which studies the physiological properties of cells , as well as their behaviours , interactions, and environment ; this is done both on a microscopic and molecular level. Cell biology researches bot...

Developmental biology

Developmental biology is the study of the process by which organisms grow and develop. Modern developmental biology studies the genetic control of cell growth , differentiation and " morphogenesis ," which is the process that gives rise to tissues , organs and anatomy . Embryology is...

Evolutionary biology

Evolutionary biology is a subfield of biology concerned with the origin and descent of species , as well as their change over time, i.e. their evolution . One who studies evolutionary biology is known as an evolutionary biologist , or less frequently evolutionist . Evolutionary biology ...

Evolutionary developmental biology

Evolutionary developmental biology (often referred to as ' evo-devo' or evolution of development ) is a field of biology that compares the developmental processes of different animals in an attempt to determine the ancestral relationship between organisms and how developmental processe...

Marine biology

Marine biology is the study of animal and plant life within saltwater ecosystems . Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology deals with those species in which life is spent only (or ma...

Mathematical biology

Mathematical biology or biomathematics is an interdisciplinary field of academic study which aims at modelling natural, biological processes using mathematical techniques and tools. It has both practical and theoretical applications in biological research. Contents showTocToggl...

Molecular biology

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology , particularly genetics and biochemistry . Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the int...

Structural biology

Structural biology is the study of the architecture and shape of biological macromolecules -- proteins and nucleic acids in particular--and what causes them to have the structures they have. This subject is of great interest to biologists, because macromolecules carry out most of the functio...

Systems biology

Systems biology is an academic field that seeks to integrate biological data as an attempt to understand how biological systems function. By studying the relationships and interactions between various parts of a biological system (e.g. organelles , cells , physiological systems , organi...

Unsolved problems in biology
