What This Document Is
This document is a lab guide for BSC 1005L: Biological Principles for Non-Majors Lab, specifically focusing on plant pigments and the process of photosynthesis. It combines pre-lab questions designed to assess foundational understanding with post-lab questions based on an exercise involving harmful algal blooms. The guide supports a hands-on investigation into the factors influencing photosynthetic rates and the ecological consequences of nutrient imbalances.
Why This Document Matters
This guide is essential for students enrolled in BSC 1005L. It prepares students for a lab session by prompting them to consider key concepts *before* the experiment, and then reinforces learning through data analysis and interpretation. Understanding photosynthesis is fundamental to biology, and the algal bloom exercise connects this process to real-world environmental issues. It’s used during the lab period to guide experimentation and data recording, and afterwards to analyze results.
Common Limitations or Challenges
This document provides a framework for understanding plant pigments, photosynthesis, and algal blooms, but it does not *perform* the lab experiment for you. It requires active participation in the lab, careful data collection, and independent thought to answer the post-lab questions effectively. It also assumes a basic understanding of biological concepts covered in the course lectures.
What This Document Provides
This guide includes:
* Pre-lab questions covering the colors and light absorption properties of chlorophyll A, chlorophyll B, carotene, xanthophyll, and anthocyanin.
* A prompt to explain the relationship between light absorption/reflection and pigment color.
* A photosynthesis equation and questions about measuring photosynthetic rate.
* An explanation of leaf color changes in deciduous trees during the fall.
* A discussion of the endosymbiotic theory relating to chloroplasts and mitochondria.
* Data tables and questions related to an exercise on harmful algal blooms, including nitrogen, phosphorus, and chlorophyll A levels over time.
* Post-lab questions requiring graph creation and data interpretation related to algal bloom trends.
This preview *does not* include the completed graphs, answers to the post-lab questions, or the full experimental procedure.
