Histology is the microscopic study of the structure of tissues
using special staining techniques combined with light and electron
microscopy.
Note: Electron microscopy is a more modern technique than simple
(light) microscopy and has the advantage of being able to magnify
even smaller structures so that they can be comfortably and reliably
studied in the laboratory.
An example of histology is the study of structures within a single cell.
A cell is the basic unit of living organisms (both plants and animals)
that is capable of
reproducing itself
exactly.
That
is,
there are
components within cells (organelles), but they do not reproduce themselves
independently of the cell(s) of which they are a part.
See the Revision
page about Cell
Structure for further information about the microscopic structures
within all animal cells.
