A student studies grasses and flowers at the Konza Prairie Biological Station in Kansas.

Botany is the general study of plants and plant-like organisms from microscopic algae to giant redwoods, from mushrooming fungi to flowering angiosperms. Plant anatomy, how plants grow and develop, and how they survive and interrelate within their environments are topics of study. For students who like the outdoors, a career in plant ecology, taxonomy, or forestry might be appealing. Students attracted to the beauty and design of the microscopic world might enjoy a career in plant anatomy or plant developmental biology. Those interested in chemistry might enjoy plant biochemistry, molecular biology, or plant biotechnology. Those intrigued by plant diseases might become plant pathologists and the mathematically oriented might explore systems ecology, genetics, or plant biotechnology.

The botany curriculum begins with a solid foundation in mathematics, the biological sciences, chemistry, organic chemistry, physics, evolution, and genetics. Botany emphasizing terrestrial plant studies including plant systematics, anatomy, and ecology, biochemistry, and earth sciences round out the core. Botany students also take liberal arts and communications courses to give breadth to their education.

Department of Biology Undergraduate Programs

Effective Fall 2023

To be qualified for graduation, students in the Biological Science major must have a minimum grade of C- in each of their biological, physical science, and mathematical courses used to meet requirements for the major. This applies to courses taken as substitutions for meeting these requirements. The minimum scholastic average acceptable for graduation is 2.000 computed only for courses attempted at CSU.

Distinctive Requirements for Degree Program:
TO PREPARE FOR FIRST SEMESTER:   The curriculum for the Biological Sciences major ‐ Botany concentration assumes students enter college prepared to take calculus.  Entering students who are not prepared to take calculus will need to fulfill pre‐calculus requirements in the first semester.  Talk to your advisor.  LIFE 102 requires high school chemistry as a prerequisite; CHEM 111 requires Algebra II as a prerequisite (this prerequisite is met by having Algebra II by test credit, transfer credit, or placement out of MATH 117 and MATH 118 on Math Placement Exam). C or better in all biological, physical science, and mathematical courses used to meet requirements for the major.  Term 4 may have to be adjusted if the student chooses 2 semesters of Organic Chemistry, do not attempt more than three science and math courses per term.  It is recommended that you do not take BZ 310 and BZ 350 together.
