Question

what is the function of thylakoids in the light reactions? they are involved in respiration. they produce carbon dioxide. they store chlorophyll and capture light energy. they synthesize sugar directly.

Explanation:

Thylakoids are structures in chloroplasts. Chlorophyll is located in thylakoid membranes and captures light - energy during the light - reactions of photosynthesis. They are not involved in respiration, do not produce carbon dioxide in the light - reactions, and do not synthesize sugar directly (sugar synthesis occurs in the Calvin cycle).

Answer:

They store chlorophyll and capture light energy.
