Study the process of transpiration/transpiration pull and the role it plays in water/nutrient movement in plants. Learn about 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. Examine the location/density of stomata from a leaf surface by preparing a stomatal peel.
