-Light is categorized into a light spectrum by wavelength. What is the range of visible light?
- -400-700 nanometers
-Both the stroma and grana are found inside the inner membrane of the chloroplast. Which
option correctly describes how the stroma and grana are different? - -The stroma is a gel-
like fluid, and grana are stacks of thylakoid membranes.
-Where in the chloroplast is chlorophyll located? - -in the thylakoid membrane
-What are light-dependent reactions? - -a series of reactions that converts light energy to
chemical energy
-What are light-independent reactions? - -a series of reactions that converts carbon
dioxide to glucose
