how will you prove that light is necessary for photosynthesis
Answers
Answer:
Light provides energy for the synthesis of glucose from carbon dioxide and water during photosynthesis. ... During light reaction, the chlorophyll entraps light and the solar energy is converted into chemical energy in the form of ATP molecules. This can happen because light energy is used to split water.
Hope this helps ;-) Have a good day ;-)
Answer:
Result- Starch is present in the exposed leaf. Conclusion- Leaf exposed to sunlight give iodine test, proving that sunlight is necessary for photosynthesis.
Explanation:
When you put iodine on the leaves, one of them will turn blue-black and the other will be a reddish-brown. Iodine is an indicator that turns blue-black in the presence of starch. The leaf that was in the light turns blue-black, which demonstrates that the leaf has been performing photosynthesis and producing starch.
