which is the site of the light-dependent reactions of photosynthesis?

a) mitochondria
b ) stomata
c ) stroma
d ) thylakoids

Correct D) Thylakoids

A thylakoid membrane is a sheet like structure that serve as a site for the light-dependent photosynthesis reactions in plants and cyanobacteria. It contains chlorophyll pigments which is used to absorb light and use it in biochemical reactions of the plants.

In plants two types of photo-system takes place photo-system I and photo-system II which are located in the thylakoid membrane of the chloroplast.

Photo-system I and Photo-system II are the protein complex that absorb photons and use that energy to create an electron transport chain, which produces  energy in the form of ATP.

i'm pretty sure it's spores
