Question 35
The following experiment was carried out to investigate the conditions needed for photosynthesis. Two identical plants were each placed in a bell jar. Set-up A contained a beaker with sodium hydroxide and soda lime to absorb carbon dioxide in the air. Set-up B contained a beaker of water and pebbles. Both set-ups were placed in sunlight for several hours. A leaf is taken from each of these plants and tested for starch. Predict what you would observe.
