Students will study the process of transpiration/transpiration pull and the role it plays in water/nutrient movement in plants. They will study the role of stomata in relation to the transpiration process using a potometer to examine the rate of transpiration in a bean seedling under a select set of environmental conditions. They will also examine the location/density of stomata from a leaf surface by preparing a stomatal peel. Lastly students will design and conduct an experiment to show how altering an environmental condition may affect the rate of transpiration. Meets AP Science Practices 1, 2, 4, 6, and 7, and Big Idea 4. Materials provided for 32 students in eight lab groups.
