This teaching module allows students to explore the role of stomata in regulating leaf temperature and water loss from plants under different environmental and climatic conditions.
Students will observe the nature and distribution of stomata of plants growing under varying temperature conditions and use the data to quantify differences in these plants. This includes a complete laboratory activity plan with background information in the form of a reading and links to other relevant readings and videos.
Use this tool to help students find answers to:
- What is abiotic stress? How does abiotic stress affect plant physiology?
- How does stomatal conductance change in heat-stressed plants?
