This lab course explores plants and plant products of economic importance through hands-on activities. Aspects related to the botany and ethnobotany of economically important plant species will be covered including taxonomy, anatomy, physiology, ecology, conservation, human uses, social and environmental issues, and roles in the economy.

Economic Botany is the study of plants of economic importance. The Economic Botany Lab course is the optional laboratory component for the PB 345 Economic Botany lecture course, and as such is part of the Department of Plant and Mircobial Biology’s ethnobotany offerings. Ethnobotany is the interdisciplinary study of the relationship between plants and people. Aspects related to the botany and ethnobotany of economically important plant species will be covered, including their taxonomy, anatomy, physiology, ecology, conservation, human uses, and roles in the economy.

Through the study of plants and plant products used cross-culturally, students learn that the earth’s botanical diversity has provided for a vast array of human needs, and continues to today. The laboratory activities add a hands-on component to the material learned in the lecture course. Students have the opportunity to examine plant specimens and plant products of economic importance. Additionally, students learn about the production processes through activities such as papermaking, making and using plant-derived dyes, and growing plant species of economic importance.

The course has been offered once in the Department of Plant and Microbial Biology as an upperlevel Special Topics course (PB 495), had good interest from our Plant Biology students for its first offering, and was very well received by these students. This course makes a substantial contribution to the departmental initiative to expand the ethnobotany emphasis within the undergraduate Plant Biology program. This course is the first upper-level undergraduate ethnobotany lab course to be offered in the department. The course is open to all interested NCSU students who have taken one of the prerequisite introductory Biology or Plant Biology courses, and are or have been enrolled in the PB 345 Economic Botany lecture course, which is a co-requisite.

Plant and Microbial Biology has accounted for the necessary lab materials and supplies to run this lab as part of its yearly offerings. The department has sufficient greenhouse space to grow the plants required for this course. The course is part of the faculty member’s regular teaching load.

Student Learning Outcomes

At the conclusion of the semester, students in Economic Botany Lab should be able to:

1. Describe the taxonomic diversity of economically important plants.

2. Explain the impact that plants and plant products have on various aspects of human life.

3. Identify the aspects of plant anatomy and physiology that make them valuable to humans.

4. Describe the importance of maintaining plant genetic diversity.

5. Relate the uses of economically important plants to social and environmental issues.

Evaluation MethodWeighting/Points for EachDetails
Each student is expected to actively participate in all lab activities and contribute to in-lab discussions each week.
Other5%Lab Cleanliness
Students will be evaluated on the cleanliness of their workspace each week. All materials should be put away and workspaces should be clear of debris at the conclusion of each lab.
Other20%Laboratory Notebook
Lab notebooks should be kept with detailed lab activity protocols and results recorded weekly. Notebooks will be reviewed everyother week (total of 6 reviews), and submitted for final grading on 4/30
Other30%Group Project
There are three group projects, for which students will work in teams. Each project is worth 10% of the total course grade. The Biodiversity Inventory and the Market Inventory should each be submitted as spreadsheets, both in hardcopy and digital formats, and should each include an accompanying data summary. Examples of submission formats will be provided. The Economic Botany Garden Design should be submitted in both hardcopy and digital formats (by email), with an accompanying spreadsheet of plant species for the garden. While students work in teams, each student is expected to individually submit their own work for evaluation and grading.
There are four quizzes that assess students’ knowledge of plant products and their production, as well as the identification of plant specimens of species of economic importance. These quizzes will be administered at the beginning of the lab period.
