The Biology Department occupies seven large buildings. The Biology tour website contains a map and describes the laboratories in these buildings:
- Rebstock Hall, the original home of the department, is flanked to the east by the Monsanto Building, Wilson Hall and the McDonnell Hall, and to the west by the Busch Building, the Life Sciences Building, and the Jeanette Goldfarb Plant Growth Facility.
- The Goldfarb Facility includes greenhouse rooms, growth chambers, and a plant tissue culture facility.
- Computers in individual laboratories are linked to the internet in the Biology Department Computer Facility.
- The Life Sciences Building also houses the Natural Sciences Learning Center with an array of computers for students in undergraduate Biology courses.
- The website for the Natural Sciences Learning Center contains additional information about the Department of Biology.
- The Departmental Imaging Facility includes two Laser Scanning Confocal Fluorescent microscopes, a computational deconvolution fluorescent microscope, a three-channel (DAPI-GFP-Texas Red) epifluorescent microscope and wetlab facilities for sample slide preparation.
