Photosynthesis and Starch

The video explains how plants produce glucose through photosynthesis, requiring light and carbon dioxide. An experiment with geranium plants demonstrates the necessity of these elements. Plants are placed under different conditions to observe starch production. The results show that both light and carbon dioxide are essential for photosynthesis. The video also discusses the industrial use of starch, particularly in paper manufacturing.

What are the two important ingredients required for photosynthesis?

Describe the conditions under which the first geranium plant was kept during the experiment.

What was the purpose of covering the leaves in iodine solution?

Explain why the first and second leaves did not turn the iodine blue.
