Question

In the process ot photosynthesis, plants use carbon dioxide, water, and energy to form sugars and oxygen. Which of the following best explains how plants follow the Law of Conservation of Mass during photosynthesis?

A. The reaction uses energy to produce a product without energy.

B.A gas and a liquid (water) use energy to produce a solid (sugar).

C.The amount of each element that begins photosynthesis equals the
amount of each element that Is produced.

D.The amount of sugars at the beginning of photosynthesis equals the
amount of oxygen that is produced.

Answer 1

C
Law of conservation of mass that state matter can’t be created nor destroyed

Here the actual the amount of elements that start the reaction would appear as product
Whether as actual elements that start the reactions of combine states

Simple sugar which also contains
Carbon oxygen and hydrogen
C6H12O6

Answer 2

C.

Step-by-step explanation:

The amount of each element that begins photosynthesis equals the amount of each element that is produced best explains how plants follow the Law of Conservation of Mass during photosynthesis. This is because during photosynthesis, the carbon dioxide (CO2) taken in by the plant is combined with water (H2O) to produce glucose (C6H12O6) and oxygen (O2). The number of atoms of carbon, hydrogen, and oxygen in the reactants (CO2 and H2O) is equal to the number of atoms of these elements in the products (C6H12O6 and O2), which means that the mass of the reactants is conserved and equals the mass of the products. Therefore, the Law of Conservation of Mass is followed during photosynthesis.
