Which of the following does not occur during photosynthesis?
Energy from sunlight is absorbed
Carbondioxide is evolved
Glucose is synthesized
Oxygen is given
water is split

Explanation

6CO\(_2\) + 12H\(_2\)O + light energy \(\to\) C\(_6\)H\(_{12}\)O\(_6\) + 6O\(_2\) + 6H\(_2\)O

This is the equation for photosynthesis. Note that carbondioxide is not evolved in these reactions.
