Module 5—Photosynthesis and Cellular Respiration
Lesson 2—Light-Dependent Reactions
Get Focused
You may wonder what role plants play in supporting your life on Earth, other than being an obvious supplier of oxygen through photosynthesis. Plants are used for making medicines, perfumes, lotions, clothes, paper, and buildings. People also use plants as a source of amino acids, food energy, and oxygen. In short, plants are a pretty big deal.
A knowledge of photosynthesis may become valuable in the future if Earth experiences food or fuel shortages. By understanding photosynthesis, technologies that could help alleviate these shortages can be explored.
What is the first thing you think of when you hear the word photosynthesis? Some words that come to mind might be green, plants, and
sun. Plants do require sunlight to perform one part of photosynthesis. You will be studying the light-dependent reactions of plants.
In this lesson you will explore the following essential questions:
- How does the energy from light flow through living systems?
- How does oxygen become a product of photosynthesis?
