Biology (B.S.)

Biology (B.S.)

Degree: Bachelor of Science

Major: Biology

Concentration: None

Total Hours: 120

The Major in Biology supports the departmental mission in that students are exposed to current scientific concepts and principles. Moreover, students spend a significant amount of their educational time in the laboratory or field. By the actual performance of methods and techniques, they can engage in internal research projects or be competitive for external summer research internships. The biology degree offers seven concentrations in (see below):

  1. Cell and Molecular Biology
  2. Ecology
  3. Aquatic Biology
  4. Vertebrate Zoology
  5. Invertebrate Zoology
  6. Pre-health Professional
  7. Pre-medical Technology

After graduation, they can effectively compete for jobs or move into graduate or professional schools. As the study of life, Biology requires a thorough understanding of the underlying chemical and physical principles governing all life processes. Lamar students attracted to this field are well equipped to enter the professions of medicine, dentistry or one of the other career paths listed below in this section. Students are equally prepared for environmentally or biotechnology related careers in various governmental agencies, private companies, or academia. Students interested in further education leading to an advanced degree in biology are also well prepared. Those interested in teaching in secondary education (grades 8 –12) should consult the section on B.S. Biology with teaching certificate.

Recommended Minimum Program of Study – B.S. Biology: The following is a recommended program of study for completion of the B.S. Biology degree plan in the minimum semester hours with the specified option. Additional requirements may be required for specialized areas, i.e. certain minor requirements, preparation for graduate school, certifications, or licenses. Please see a Biology Advisor or the Department Chair for advising details.

Certification to teach Biology can be obtained along with a B.S. in Biology. Consult with the Biology Department Chair for specific information. A list of Biology courses for certification is available in the departmental office.

Biology Bachelor of Science - Concentration in Medical Technology

The medical technologist performs the laboratory tests required by physicians in order to properly diagnose and treat patients. Most technologists find employment in hospitals, clinics or blood banks. In addition, manufacturing and sales of  medical products are providing new career opportunities for medical technologists. A long-term shortage of clinical laboratory scientists has placed a premium on certified medical technologists nationwide, and employment opportunities in the field are expected to remain very good in the future.

Students completing the pre-medical technology emphasis will receive a Bachelor of Science in Biology that emphasizes the course work needed to compete for acceptance into hospital programs in the clinical laboratory sciences. Most hospital programs last for one or occasionally two years. During this time, students receive laboratory training in practical aspects of the clinical laboratory sciences. In addition, a certification exam must be passed to be employed as a clinical laboratory scientist in most states.

Students pursuing a concentration in Medical Technology should take the course recommended for that concentration (see the Concentration list above), as well as additional courses decided upon in consultation with the program director.  Entry into hospital programs is competitive, and completion of these courses will best-prepare students for acceptance into hospital programs.  A list of hospital programs for the state of Texas is provided below.

Students interested in these programs should contact Dr. Randall Terry for detailed advising (Maes 101A,, (409) 880-8256).
