Cell biology Concept of cell biology
It is the science that studies the basic units of all living
beings, called cells. Cell biology is also called cytology.
Cell: From the Latin "cellula", diminutive of cella, "cell".
Objectives
Cell observation by microscopy.
Optical microscopy
Electron microscopy
Scanning microscopy
Methods
Cytochemical and histochemical
technique.
Cell culture.
Fractionation of cellular content.
Relationship with other sciences
Molecular biology
Embryology
Cell biology
Histology
Physiology
Cell theory
The cell theory can be reduced to three fundamental postulates:
All living beings are composed of cells.
The vital functions of organisms take place within cells.
All existing cells originate from other, pre-existing cells.
Cellular Diversity
A. Neurons of the cerebral
cortex.
B. Skeletal muscle cells viewed
longitudinally.
C. Plant cells of a leaf.
D. Different cell types of the
digestive tract.
