Understanding Photosynthesis: The Key to Life on Earth
Introduction Welcome, 10th graders! Today we dive into one of the most fascinating processes in science: photosynthesis. This remarkable process is essential to life on Earth because it is how plants produce the food and oxygen that we and many other organisms need to survive. What is Photosynthesis? Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This process also produces oxygen as a byproduct. The Photosynthesis Equation The general photosynthesis equation can be simplified as follows: 6 CO 2 + 6 H 2 O + light energy → C 6 H 12 O 6 + 6 O 2 This means that six molecules of carbon dioxide and six molecules of water are converted into one molecule of glucose and six molecules of oxygen using light energy. Where Does Photosynthesis Occur? Photosynthesis occurs in the chloroplasts of plant cells, which contain a pigment called chloroph...
