QUESTION OF THE WEEK -
#10
What does the endomembrane
system of
eukaryotic cells really
look like?
The endomembrane systems of cells (rough and smooth endoplasmic reticulum, golgi apparatus) are three dimensional and change with time. In contrast, electron micrographs of cell thin sections are two dimensional and static. This present a problem for students - one has to use one's imagination to understand reality! The following links are to websites that contain micrographs, drawings and descriptions of the endomembrane stystems of cells. The more you see, the more you will understand about these complex and dynamic structures. Feel free to explore links within these links...
