Biology is the scientific study of living organisms and their interactions with one another and their environments. This science can be considered a bridge between the physical sciences and humanities, touching areas such as Chemistry, Physics, and even Social Sciences.

Cellular Biology

At the core of biology is the cell, the fundamental unit of life. Cellular biology studies the various types of cells and how they function.

Types of Cells

Types of cells, like animal cells, plant cells, and bacteria

Genetics and Evolution

Genetics explores how traits are passed from parents to offspring through genes. Evolutionary biology examines how species change over time and adapt to their environments.

Anatomy and Physiology

Anatomy studies the structure of living organisms, while physiology focuses on how these structures function. These topics are crucial for understanding health and disease.


Ecology focuses on how organisms interact with each other and their environments. It includes studies of individual organisms, populations, communities, ecosystems, and the biosphere.

Ecosystem Interactions

Microbiology is the study of microorganisms, including bacteria, viruses, fungi, and protozoa. This field has significant implications for medicine and environmental science.

Botany and Zoology

Botany is the study of plants, including their physiology, structure, and genetics. Zoology, on the other hand, focuses on animals.

Behavioral Biology

Behavioral biology examines the mechanisms behind the behavior of animals and humans, often drawing connections to Psychology.


Biotechnology involves manipulating biological systems for practical purposes. It is closely related to Applied Sciences and Engineering.


Biology is a broad and diverse field that encompasses the study of all living things and their intricate web of interactions. For more topics in the realm of science, you may explore the Overview of Science or go back to the main Encyclopedia Overview.
