This monograph is intended to provide an overview of the structure,
function, and development of the chloroplast. It should be viewed as a
beginning of the study of chloroplasts and not as an end. In keeping
with an introductory approach, abbreviations generally have not been
used, so that substance is not replaced by symbol. The principal aim has
been to provide a teaching tool to introduce students to the major
characteristics of the chloroplast, with as much emphasis on mech-
anisms as possible at this level. It was written for students with an
advanced college level education in biology and chemistry who also have
some knowl- edge of biochemistry. The fundamentals of these subj ects
cannot be included in a book of this type. However, to provide a
meaningful description of how the chloroplast works, Le., what the
mechanisms of photosynthetic reactions are, the subj ect must be dealt
with at the molecular level. Living systems are chemical systems, and
the importance of understanding these systems at the molecular level
cannot be overstated. Therefore, although attempts were made to keep the
chemistry at a relatively simple level, occasionally statements are made
that can be understood only with a sufficient background knowledge of
chemistry. It is important for students to realize in broad outline form
the functions of the chloroplast and where its functions fit into the
scheme of life.
