Undergraduate Courses

The Bachelor of Science programme in Plant and Environmental Biology is designed to equip students with in-depth knowledge of plant biology and its practical applications in addressing today’s pressing environmental issues. With increasing concerns around climate change, biodiversity loss, ecosystem degradation, and pollution, the programme trains students to understand and respond to these challenges. 

In the first year, students undergo comprehensive training in the biological sciences, to establish a strong academic foundation. In subsequent years, the curriculum explores specialized areas such as plant physiology, anatomy, genetics, ecology, phycology, mycology, and microbiology, emphasizing their relevance to industry and environmental management.

The programme integrates fieldwork, laboratory training, and research methodologies, encouraging students to apply scientific knowledge to real-world problems. With a strong focus on analytical thinking, data interpretation, and practical skills, graduates are well-prepared for careers in research, academia, environmental consultancy, conservation, and related fields that contribute to sustainable development.
