Question

During photosynthesis, an energy transformation takes place. Which one of these happens during photosynthesis?

A. Light energy turns into chemical energy.
B. Chemical energy turns into light energy.
C. Light energy turns into electrical energy.
D. Electrical energy turns into mechanical energy.

Answer 1

During photosynthesis, light energy undergoes a crucial transformation. Specifically, light energy is converted into chemical energy in the form of sugars. In this process, glucose molecules (or other sugars) are constructed from water and carbon dioxide, while oxygen is released as a byproduct1. So, the correct answer is A. Light energy turns into chemical energy.

Answer 2

During photosynthesis, light energy is transformed into chemical energy, which is used by plants to produce glucose. This is how photoautotrophs convert light into a storable form of energy in the ecosystem.

Step-by-step explanation:

During photosynthesis, light energy is converted into chemical energy. The specific energy transformation that takes place during photosynthesis is that light energy turns into chemical energy. This process allows plants and other photoautotrophs to produce glucose, which is a basic carbohydrate molecule that stores energy in its chemical bonds. This conversion is fundamental to the ecosystem as it provides the base for the food chain.

When comparing to a photovoltaic cell, where solar energy transforms into electric energy, photosynthesis operates differently by harnessing light energy directly to produce food through chemical processes in the chloroplasts.
