Light on Photosynthesis

Paper Summary:

The paper discusses a study where the goal is to measure the rate of photosynthesis that Elodea shoots have when they are exposed to specific light sources and distances. The paper hypothesizes that the quality of the light, not the quantity of the light, makes a difference, and having a lot more light will not necessarily make photosynthesis occur any faster. The paper lists the materials and methods used and explains the results that indicate that the rate of photosynthesis with a 100-watt bulb is much higher than the rates with 150-watt bulbs. The paper includes three charts of results.

From the Paper:

"People have been interested in plants for hundreds of years, and a lot of people study them and grow them as hobbies. There are many different things that affect how a plant grows. Some of these are soil, temperature, oxygen, water, and nutrients (The soil, 2004). Light is also important for a growing plant because it must have light for photosynthesis to take place. In the simplest of terms, soil and light are the most important things for most experiments discussed and created with plants. The soil has a certain amount of water in it, and how much depends on what kind of soil it is. Different soils have different structures, and this determines how much water drains through and how much stays in the soil for the plant to use (The soil, 2004)."
