Question

Using your knowledge of ohotosynthesis and cellualar repiration explain why radish seeds grown without sublight lose weight and what happens to that weight?

Answer 1

When when the raddish seeds are grown in absence of Sunlight, then the photosynthesis process is not found in the raddish seeds. Hence there is not found the synthesis of sugar molecules. But there is found respiration process. Because the respiration is independent of sunlight. Respiration leads to break down sugar molecules into carbon dioxide for producing energy.

Hence the weight of the raddish seeds are decreased due to decrease in sugar molecule by respiration and absence of photosynthesis.
