Undergraduate Programs


Bachelor of Science in Biology


This degree includes a general option in biology and six additional options for those desiring a more specialized program.

Biology (code BIOLBS01) (120 units)


This degree major is designed for students pursuing careers that involve the study of life; it is especially appropriate for those contemplating graduate work in the biological sciences. This option gives the student a broad background involving coursework in most of the major areas of biology, without requiring specialization in any one particular field. Students in this option have more elective courses in their major than in the other, more specialized, options, which enables them to partially concentrate their studies in a particular area if they so choose. Because of this, students may not combine this option with any other in the B.S. in Biology nor with the B.S. in Marine Biology or Microbiology as part of a dual major. This option requires approximately 82-84 units in the major, of which 39-41 are in lower division and 43 are in upper division. All students must achieve at least a 2.0 grade-point average in each of the following: 1. the entire college record, 2. all units attempted at CSULB, 3. all courses in the major, and 4. all upper division courses in the major completed at CSULB.

Lower Division: BIOL 111, 111L, 212, 212L, 213, 213L, 260; CHEM 111A,B; MATH 119A or 122, 119B or 123; PHYS 100A or 151, 100B or 152. The following courses do not meet any specific or elective requirements for this major: BIOL 153, 153L, 200, 200L, 204, 205, 205L, 207, 208; MICR 101 and 200.

Upper Division: CHEM 322A,B and 323A,B; at least 34 units in biological science including BIOL 312, 340, 345, 345L, 350, 370, 480; one of BIOL 313, 316, 324; one of BIOL 427, 439; and 9 additional units selected from upper division courses in the Department of Biological Sciences. At least two of the courses selected to fulfill these additional units must have numbers between 410-499. Either CHEM 441A,B or 448 will count toward these additional 9 units. Up to 6 of these additional units may be substituted from courses in other departments in the College of Natural Sciences and Mathematics upon approval by the undergraduate advisor. Students may use from 1-3 units of BIOL or MICR 496 towards the 9 additional units of upper division course work but only with prior permission of the advisor for this option. The following courses do not meet any specific or elective requirements for this major: BIOL 301, 304, 308, 309I, MICR 300I, and NSCI 492.

Option in Biology Education (code BIOLBS02) (120 units)


This option is designed solely for students who wish to become secondary school Biology teachers. This option requires 82-92 units in the major, of which 50-52 are lower division and 32-40 are upper division. Prospective students should consult the Single Subject Science Education Advisor in the Department of Science Education early to plan their program.

Completion of the Biological Sciences Concentration meets the subject matter competence requirement for the Single Subject Preliminary Credential in Biology (code 184). In addition to meeting the subject matter competence requirement for the Preliminary Credential, prospective Biology teachers are also required to complete 44 units of professional preparation in the Single Subject Credential Program, including student teaching. Students may begin the professional preparation courses as early as the junior year. With careful planning, it is possible to complete many of the credential program courses, as an undergraduate. Courses may also be started as post-baccalaureate student. Refer to the Single Subject Teacher Education section of this Catalog or the Single Subject Credential Program website (www.ced.csulb.edu/single-subject) for a description of the professional preparation requirements, courses, and application procedures.

The Biological Sciences Subject Matter Program is being revised to meet new state standards. When the revised program has been approved by the Commission on Teacher Credentialing, the new course requirements will be in effect and supersede current requirements.

All students must achieve at least a 2.0 grade-point average in each of the following: 1. the entire college record, 2. all units attempted at CSULB, 3. all courses in the major, and 4. all upper division courses in the major completed at CSULB.

Certificate in Biotechnology (code BIOLCT01)


Biotechnology is a rapidly growing field which encompasses many domains of science. Specifically, biotechnology refers to a process which ultimately yields a product. The products can be loosely subdivided into five categories; biological organisms with novel traits, DNAs, RNAs, proteins, and compounds. The Undergraduate Certificate in Biotechnology is the integrated use of specific offerings of the College of Natural Sciences and Mathematics, including the departments of Biological Sciences and Chemistry and Biochemistry. Laboratory facilities and selected courses will serve to provide a fundamental background in the theory and techniques of biotechnology. The certificate may be earned in conjunction with or subsequent to a baccalaureate degree. Courses offered for the certificate may be used to satisfy, as appropriate, major or minor requirements.

Prerequisites for Admission
