       Eucaryotic Cells

Eucaryotes evolved more recently than procaryotes, and they obviously represent a higher level of organization.

More specialization is seen within the cell, and there is more compartmentalization of the cell chemistry. Listed in the table below are eleven major components of a eucaryotic cell, which includes plant as well as animal cells. The photomicrograph on Page 1 shows a typical animal cell - a secretory cell from the pancreas of a bat.

In the schematic drawing to the side, labels indicate major features that are visible in the chapter-opening photomicrograph.

The round dark objects, called zymogen granules, contain enzymes packaged for export from the cell.
