Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
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.
