Q7. Distinguish between Photosynthesis and Respiration. Write the chemical
equation for each.
Answers
Photosynthesis:-
(1) Occurs only in phototrophs (all green plants, algae and some bacteria).
(2) The entire process occurs in Chloroplasts.
(3) Carbon dioxide, water and light energy are the reactants of this process.
(4) Glucose, oxygen and water are the by-products.
(5) Undergoes Anabolic Process.
(6) Producing food and capturing energy.
(7) In this process, food is synthesized by capturing energy.
(8) It is an endothermic reaction as it requires energy.
(9) This process requires sunlight since photosynthesis occurs only in the presence of sunlight.
Example:- The chemical reaction of photosynthesis is 6CO2 + 6H2O → C6H12O6+ 6O2.
Respiration:-
(1) Occurs in all living organisms.
(2) The entire process occurs in Mitochondria.
(3) Glucose and oxygen are the reactants of this process.
(4) Carbon dioxide, water, and energy (ATP) are the by-products.
(5) Undergoes Catabolic Process.
(6) Oxygen is taken in and carbon dioxide is liberated out.
(7) In this process, food particles are broken down to release energy.
(8) It is an exergonic reaction as energy is released.
(9) This process does not require sunlight since cellular respiration occurs all the time.
Example:- The chemical reaction of cellular Respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O.
