Answer 1

Explanation:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product

Answer 2

Observation: - The ethyl alcohol breaks the chlorophyll in the leaves and makes them white in color, and iodine turns the starch into a blue-black color.

.

- So starch is produced only in the leaves which are exposed to sunlight, and this proves that sunlight is very essential for plants to do photosynthesis
