Question

A scientist observed that in the presence of light, plants use carbon dioxide and water to make glucose and oxygen. This chemical process is called photosynthesis. Which type of energy is transformed into chemical energy, based on the scientist's observations? Answer options with 4 options A. light energy from the sun B. kinetic energy from water C. chemical energy from oxygen D. heat energy from the environment

Answer 1

Option A, light energy from the sun

Explanation:

In the process of photosynthesis, the energy from sun in the form of light and heat is taken to undergo glycolysis and prepare glucose/starch (chemical).

Thus, the light and heat energy of sun is converted into the chemical energy.

Option B and C are incorrect because no kinetic energy or chemical energy is taken from any source.

Option D is also incorrect because heat is taken but it is not taken from the surrounding environment. The source of heat energy is sun.

Thus, only option A is correct
