 Oxygen liberated during photosynthesis comes from
(a) water
(b) chlorophyll
(c) carbon dioxide
(d) glucose

Answers (1)

Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.
Chlorophyll absorbs ultraviolet rays breaks the water molecules and forms oxygen. So, we get oxygen from the water molecule.

6CO_{2} + 6 H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}

Hence, (a) is the correct option.
