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.
Photosynthesis. During photosynthesis, a process that occurs in plants and in cyanobacteria and also in purple photosynthetic bacteria, light energy is converted into chemical energy. The overall process is described by the chemical equation: CO2 + H2O â (CH2O) +O2 (requires photons, hv) (1).
