Answer:
The correct answer is - Mass.
Explanation:
A chemical equation represents the change in the complete composition during the chemical reaction. The reactants and the mass of the products remain constant in the balanced equation which means there is no loss of mass take place in a chemical reaction.
Chemical reactions follow the law of conservation of mass which means like energy mass can not be destroyed or created and represent by the balanced chemical equation.
1) Carbon dioxide
The carbon atoms present in CO2 are used by the plant in the formation of the organic molecular group (sugar).
2) Chlorophyll
Photosynthetic pigments present in chloroplasts, responsible for absorbing light from wavelengths between blue and yellow and reflecting different shades of green
3) Oxygen
Oxygen is the end product of photosynthesis, the result of the breakdown process of water molecules.
4) Stomata
Stomates have the function of performing gas exchange between the plant and the external environment. This structure is also responsible for the perspiration of the plant.
5) Sunlight
Energy source for the process of transforming light energy into chemical energy
6) Glucose
Final product of photosynthesis. Molecule that will be used by the plant to maintain its vital functions.
7) Water
Oxygen source that will be released as a gas at the end of the process.
