You will determine how carbon dioxide affects the rate of photosynthesis by conducting an experiment.
After completing this tutorial, you will be able to complete the following:
Photosynthesis is a series of chemical reactions by which plants obtain their energy
In this process, sunlight is absorbed by chlorophyll inside the chloroplasts of plant cells. In order for photosynthesis to take place, the plant must take in carbon dioxide and water. As a result of photosynthesis, carbohydrates and oxygen are produced.
The rate at which a plant conducts photosynthesis is not always the same. Various factors influence the rate at which photosynthesis takes place, including the amount of carbon dioxide present, the amount of water, the chlorophyll concentration, and light intensity. These factors can increase the rate of photosynthesis. However, the rate of photosynthesis cannot increase indefinitely. Once a certain level is reached, the rate of photosynthesis remains constant.
