Detailed explanation-1: -In photosynthesis, the chemical energy produced is stored in the form of sugars, which is created from water and carbon dioxide. As we can see, sugar (glucose) is produced by this process. This glucose is further polymerized to form compounds such as starch.

Detailed explanation-2: -Explanation: The food prepared by green leaves during photosynthesis process is glucose. Glucose formed in photosynthesis soon gets converted into starch. This glucose is utilised by the plant and extra glucose is stored in form of starch in the leaves.

Detailed explanation-3: -In 1862 and 1864 he proved that the starch present in the chloroplasts results from the absorption of carbon dioxide, and he established that starch is the first visible product of photosynthesis.

Detailed explanation-4: -Starch is the main and first product formed during photosynthesis because the simple sugar formed is partly used by the plant and excess of it is converted into starch immediately for storage and the starch is transported to other parts of the plant through the phloem vessels for storage.

Detailed explanation-5: -Sachs (1854) provided the evidence that green plant parts produce glucose which is stores in the form of starch starch is first visible product of photosynthesis.
