How do u test for starch in plants

Investigating photosynthesis – starch and chlorophyll

During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:

transported to the growing parts of the plant for use in respiration

transformed into cellulose, proteins and oils

turned into starch for storage

Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.

Explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
