2.Explain how light is essential for photosynthesis?

Answer 1

Answer:

-Experiment to prove the necessity of carbon dioxide in photosynthesis - definition. ... Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle. Leave the plant sunlight. After few hours, perform a starch test to this and another leaf of the same plant.

Answer 2

Explanation:

1. photosynthesis is a process used by plants and other organisms to convert light energy normally from the sun into chemical energy that can be later released to fuel the organisms activities this chemical energy is stored in carbohydrate molecules such as Sugars which are synthesised from carbon dioxide and water .
2. light is essential for photosynthesis because the uncovered region of the leaf receive sunlight and forms photosynthesis the leaf their for turns blue black after putting iodine in this area due to the production of starch ..... ..........................hope this helps you
