The water molecules labeled A in Figure 4.1 are going to the thylakoids to take part in Light-Dependent Reactions.
The interior membrane structure of the chloroplast is composed of interconnecting disc-like sacs called thylakoids. They are discovered floating in the stroma. Grana are stacks of thylakoids that are arranged in a particular way. The thylakoid membrane contains chlorophyll, a photosynthetic pigment that absorbs light during photosynthesis.
The interior membranes of cyanobacteria and chloroplasts, known as thylakoids, serve as a platform for the photochemical reactions that take place during photosynthesis.
