Cell Biology
Cells are the basic structural and functional units of all known living organisms. Thus,
the studies of cells can contribute to an integrated understanding of tissues and
organisms. Cell biology is a field of science that focuses on the study of cells
properties, including their physiology, their structure and function, and their life cycle.
Mitosis and meiosis are two types of fission that cells replicate genetic material in
preparation for cell division. Body cells contain two sets of chromosomes (one set
from each parent). It is very important to understand the components of cells and
how cells work because it is the fundamental of all biological sciences and is essential
for research in cancerization, and other diseases.
Antonie van Leeuwenhoek firstly described the apparent movement of live cells.
Afterwards Robert Hooke’s first observed the plant-cell walls in slices of cork. In the
1830s, plant scientist Matthias Schleiden and animal scientist, Theodor Schwann,
provided the first clearly stated definition of the cell. They thought that all living
creatures, both simple and complex, are made out of one or more cells, which are
the structural and functional units of life.
