The cell is the basic unit of biology. Every organism either consists of cells or is itself a single cell.
A revolution in biology has brought with it tremendous advances in our understanding of how cells are constructed and how they carry out all the intricate functions necessary for life.
Particularly significant is the dynamic nature of the cell, as evidenced by its capacity to grow, reproduce, and become specialised, its ability to respond to stimuli and adapt to changes in its environment.
Cell biology itself is changing, as scientists from a variety of related disciplines focus their efforts on the common objective of understanding more adequately how cells work.
The convergence of cytology, genetics, and bio-chemistry has made modern cell biology one of the most exciting and dynamic disciplines in contemporary biology.
