b) Chlorophyll CO2 H2 O
c) O2 Starch Cellulose
d) Water O2 Chlorophyll

Answer 1

Answer:

CO2 H2 O O2 is answer of this question

Answer 2

Answer: Option D) Water, O2, Chlorophyll.

Explanation:

• Photosynthesis is a process in which plants synthesise their own food in the presence of sunlight and chlorophyll.
• It is a process in which light energy is converted into chemical energy.
• In this process, plants use carbon dioxide and water in the presence of sunlight and chlorophyll to form glucose and oxygen.
• During photosynthesis water undergoes photolysis.
• Oxygen is the major product formed during photosynthesis.
• Chlorophyll is essential for the process of photosynthesis but remains unchanged after the reaction.
• Thus, option d is the correct answer.
• Water is used up, oxygen is the product, and chlorophyll is essential but remains unchanged.
