7.The equation below shows a process that occurs in all green plants.

carbon dioxide + water + energy → glucose + oxygen

Which statement about this process is true and supported by the equation?

Ⓐ The process does not follow the law of conservation of mass
Ⓑ The process is called cellular respiration
Ⓒ The process does follow the law of conservation of mass and energy is not in the product
Ⓓ The process follows the law of conservation of mass and energy is found in the product

This question depicts PHOTOSYNTHESIS, which is the process employed by green plants to manufacture their food in form of sugars (glucose). The general equation, which was given in the question is as follows:

6CO2 + 6H2O + energy → C6H12O6 + 6O2

This chemical reaction follows the LAW OF CONSERVATION OF MASS, which states that the amount of matter in reactant must equate that of the product. In this case, each element contains the same number of atoms in both reactant side and product side.

Also, energy is contained in the product but stored in the chemical bonds of the glucose molecule formed.
