This document is a lab worksheet for BIO 182L General Biology II at Grand Canyon University, focused on the processes of transpiration and stomatal peels. It’s designed for students to record observations, perform calculations, and answer questions relating to a hands-on laboratory exercise.
This worksheet is a key component of understanding plant physiology, specifically how plants manage water loss and gas exchange. Students will likely use this during or immediately following a lab session to solidify their understanding of the concepts. It serves as a graded assessment of their ability to apply theoretical knowledge to experimental data.
This assignment requires students to independently synthesize information and demonstrate collegiate-level writing skills, including proper citation using GCU style. It does *not* provide background information on transpiration or stomata; students are expected to have prior knowledge.
The full worksheet includes: tables for recording transpiration data (including water height and capillary tube diameter), a space to include an Excel graph with regression line equation and R² value, questions requiring detailed explanations of transpirational pull, the influence of capillary tube size, observations from stomatal peels (upper and lower epidermis), calculations of stomata density, and questions about the advantages of stomatal arrangement and regulation of water loss. This preview only provides a glimpse of the assignment’s structure and content areas.
