BIOL 325 Plant Physiology w/Lab
A study of plant structure and function, with emphasis on the flowering plants. Includes plant cells and organelles, mineral nutrition, translocation processes, and hormonal regulation of growth, development, and reproduction. Biochemical and environmental aspects of photosynthesis are emphasized. Six hours classroom/laboratory a week. Prerequisites: One 200-level Biology course. For ENST/ENSC majors only, prerequisite is ENST 162.

BIOL 412 Coastal Biology
Through detailed study of the primary biological literature, students acquire an understanding of the methodology and philosophy of scientific research. Includes study of the formulation of hypotheses, the design of experiments or observations to test these hypotheses, and the interpretation of results. This course will normally require a major research-based presentation and/or paper and may also involve the conduct of research by students. This course satisfies the requirement for a research experience for the biology major. Prerequisites: two Biology courses numbered between 120 and 129, and one upper-level biology course.
