Plant Systematics


Code(Credit):CUTM 1464 (3-2-1)

Course Objectives

•The major features and evolutionary origins of vascular plants
•Identification of plants using dichotomous keys
•The major features and evolutionary origins of vascular plants
•Collect, preserve and identify herbarium specimens in a phylogenetic context

Learning Outcomes

Upon successful completion of this course, the student will be able to:
•Develop understanding of major patterns in the evolution of seed plants. An appreciation of seed plant diversity. A basic understanding of the principles of phylogenetic systematics.
•Define order, family, genus and species. Students will understand the process of plant.
•Pursue higher studies to get employability opportunities.
