Question

which series lists the structural components of the light - dependent reactions in order, from smallest to largest? chlorophyll thylakoid photosystem i photosystem ii chloroplast photosystem ii photosystem i thylakoid chlorophyll thylakoid chloroplast chloroplast chlorophyll thylakoid

Explanation:

Chlorophyll is a pigment molecule. Thylakoids are membrane - bound structures in chloroplasts that contain photosystems. Photosystems are large protein - pigment complexes. Chloroplast is a large organelle. So the correct order from smallest to largest is chlorophyll (molecule) < thylakoid (membrane - bound structure) < chloroplast (organelle).

Answer:

chlorophyll < thylakoid < chloroplast
