Dear Rodrigo,

When doing a search, use at least two of the search engines, I
recommend HotBot and Alta Vista. If you have time, experiment with
modified search strings. If time permits, try the other search engines
as well.

Check next sites. They have exactly the information you may need:

Devens Gust has a page devoted to the question, "Why Study
Photosynthesis?" (http://photoscience.la.asu.edu/photosyn/study.html),
that explains why photosynthesis
studies are important to many areas not immediately identified with

Try too The International Society of Photosynthesis Research:

Looking for Information with Alta Vista http://altavista.digital.com
Number of hits for word "photosynthesis": 62,020
Alta Vista does the most complete single word searches of any of the
search engines. Unfortunately, the results are too great to be
helpful. However, its searches can be modified in a couple ways. For
the original search, typing the search string "photosynthesis
+bacteria +chlorophyll +energy -sound" (quotations not needed) yields
a list of 2,382 sites. However, the words serving as modifiers are
treated as suggestions and not absolutes so it is possible that some
sites will contain some, but not all of the terms. The second way of
modifying the search is by using the "Refine" button. Here a list of
words associated with the main term show up with the percentage of
sites the words appear. The searcher can then ignore, require, or
exclude the word. The nice thing about this is that it is a refinement
to the search already done under the first method. Just by excluding
certain of the suggested words yielded a new search of 231 sites.

One of the earliest photosynthesis sites, the Arizona State University
(ASU) Photosynthesis Center site, appeared in 1995 and is maintained
by one of us (L.O.). This award-winning site,
http://photoscience.la.asu.edu/photosyn/, is very comprehensive,
showcasing not only the work of the Center, but also providing
original material and numerous links to other sites devoted to
individual and group photosynthesis research and to sites of interest
to researchers, educators, students and the general public. The
University of Illinois at Urbana-Champaign (UIUC) hosts several
important sites. A site by one of us (G)
(http://www.life.uiuc.edu/govindjee/) is much more than an individual
site as it includes information on a variety of topics, including
course web pages, a major tutorial/essay on "The Photosynthetic
Process" (by J. Whitmarsh and Govindjee), movies, photos and comments
on Robert Emerson, Eugene Rabinowitch, William Arnold, Lou Duysens and
Stacy French, and tutorial on "Photosynthesis and Time" and other
teaching materials such as slides. UIUC is also the home of a
wonderful and highly educational site of A.R. Crofts
(http://ahab.life.uiuc.edu/index.html; we will return to this site
again). The Photosynthesis
Research Unit, http://www.life.uiuc.edu/pru/homepage/text.html,
affiliated with the USDA Agricultural Research Service, covers many
areas of photosynthesis crop research. The Theoretical Biophysics
Group at UIUC is also present with an excellent site
(http://www.ks.uiuc.edu/Research/psu/psu.html) devoted to
"Light-Harvesting in Bacterial Photosynthesis." The Plant Cell Biology
group at Lund University, Sweden, http://plantcell.lu.se/, contains
much useful information and links as well as interesting pages on
"Light, Time and Micro-Organisms," imaging chlorophyll fluorescence
and much more. The Institute of Crystallography at the Free University
of Berlin has an important site devoted to X-ray structure analysis of
Photosystem I,
The Biophysics group at Leiden University hosts a couple of important
sites devoted to "Photophysical Processes in Photosynthetic Reaction
Centers" (http://www.biophys.LeidenUniv.nl/Research/RCs/) and "Energy
and Electron Transfer in Photosynthetic Membranes"
(http://www.biophys.LeidenUniv.nl/Research/PMs/). The Avron-Wilstätter
Center for Photosynthesis Research at the Weizmann Institute of
Science has a large site,
tatter_ctr.html, devoted to many areas of research.

I hope this will be helpful for you.
Good luck
