The Department of Plant and Molecular Biology, formerly known as the Department of Botany established in 1967, educates undergraduate students in current plant and molecular biological concepts and methodologies in the laboratory and the natural environment.

In addition to the Botany discipline, a new discipline, Molecular Biology and Plant Biotechnology was introduced by the Department in 2003. All biological science students admitted to the Faculty of Science are eligible to follow courses in Botany and Molecular Biology.
