Paper-Pencil vs. Performance-Based Assessment. There are many types of formal assessments used in educational settings. In this lesson, we will discuss the difference between paper-pencil assessments and performance assessments.
Photosynthesis is a chemical reaction in which light energy is converted to chemical energy in glucose. It is the means by which the energy in sunlight becomes usable to living things. carbon dioixde + water + light energy ---> glucose + oxygen + water.
These stages are known as the light-dependent reactions and light-independent reactions. Light-dependent Reactions. The first stage of photosynthesis is the light-dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power). Light-dependent Reactions.
