Challenges

1.Show locations and qualitative strength of evidence of two different processes performed by four different organisms.
2.Draw structuraly and citologically accurate figures. Lots of backgound information and images !
3.Use of color and contrast.

It wold have been cool to be a ble to use a heat map approach to show the locations. But to show the organism type was required and it was felt then that could not be combined with this color mapping.
