Is a photosynthesis a physical or chemical change?

What kind of compounds are produced in photosynthesis?

endothermic reaction
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is found in chloroplasts in plant cells , particularly the palisade and spongy mesophyll cells .

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants. Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.

The photosynthesis is the process used by plants to produce their food. In this process light energy is converted into chemical energy. As a new product is formed in this process, therefore photosynthesis is a chemical change.

Here is the chemical reaction involved: As we can see, water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

chemical change
It is a chemical change because carbon dioxide and water cannot be obtained back from glucose and oxygen.
