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.
Carbon Cycle Chemical Reactions Involved: Photosynthesis: Air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a by product. During photosynthesis plants use carbon dioxide and produce oxygen.
