What is cell Biology?

What is cell Biology?

Divisions in the biological sciences are
based on degrees of “complexity”


Starting with a living organism…

In one direction (‘downwards’) biology is
reductionist

In the other direction (‘upwards’) biology is
holostic

Biochemistry & Biophysics: study of the
structures and behaviors of molecules

Microbiology: study of prokaryotic cells and
viruses

Cell Biology: study of the structure and
function of eukaryotic cells

Developmental Biology: study of how communities
of cells form tissues, organs, and build an
organism

Anatomy & Physiology: study of the structures
and functions of tissues and organs

Zoology, Botany, Mycology, Bacteriology:
study of the organisms

Ecology: study of how organisms interact with
each other and with their environments
