Question
Which of the following is a product of photosynthesis?
- Water
- Sunlight
- Carbon dioxide
- Starch
Hint:
Starch is a product of photosynthesis.
The correct answer is: Starch
Plant synthesise glucose during the process of photosynthesis. The excess of glucose is stored in the form of starch. The first product of photosynthesis is sugar and it is converted into starch in all plants. Starch is a chain of glucose molecules which are bound together, to form a bigger molecule, which is called a polysaccharide.
