What is the waste product of photosynthesis?
a. o2
b. co2
c. h2o
d. c6h12o6

Answer : The correct option is, (a)

Explanation :

Photosynthesis : It is a chemical process which occurs in the green plants or living organism.

During photosynthesis process, the carbon dioxide reacts with water in the presence of sunlight to gives glucose and oxygen as a byproduct.  

In the photosynthesis reaction, carbon dioxide and water molecule are the reactants and glucose and oxygen are the products.

The balanced chemical reaction will be,

From the balanced reaction we conclude that the carbon dioxide and water are the reactants which are present on the left side in a reaction and glucose and oxygen are the products which are present on the right side in the reaction.

Hence, in the photosynthesis the waste product is .

c is the answer because when something is left after something evaporates that shows the chemical change.
