_____________ molecules formed during the process of __________ are converted to starch storage.
Based on your knowledge of photosynthesis, list and explain at least two factors that could lead to a negative iodine test.
First Part:
The answer will be positive.
Explanation: Starch gives positive result for iodine test. In presence of starch, iodine test provides blue-black color.
Second Part:
The answer will be glucose molecules & photosynthesis process.
Explanation: During photosynthesis, glucose is formed using light, water & CO2 that is stored as starch molecules in plants.
Third Part:
Note: Assuming this question asked about plants.
Negative iodine test will occur when amount of starch is very low. This will occur when photosynthesis is not occurring in plants & as a result plant will use stored starch. So, two factors that can resulted in negative iodine test are inadequate light & water. These two factors are essential in plants to conduct photosynthesis & absence (or inadequate amount) will hamper photosynthesis.
