Which statements are true for chloroplasts? select the three that apply. a. they are the sites of reactions that convert chemical energy from food molecules to atp. b. their inner membrane has infoldings called cristae. c. their matrix contains enzymes that function in cellular respiration. d. they have membranous sacs called thylakoids that are surrounded by a fluid called stroma. e. they contain the green pigment chlorophyll. f. they are the sites of reactions that convert solar energy into chemical energy.

The correct answers are options d, e and f.

Explanation:

Chloroplasts refer to a double-membrane bound organelles, which exhibits an internal membrane system known as the thylakoids. The thylakoids are found in a fluid known as stroma. The thylakoids are the location for undergoing light reaction and possess chlorophyll pigment.  

The captivation of solar energy takes place by the green color pigment chlorophyll, which is eventually used to generate NADPH and ATP while undergoing light reaction. Stroma is the location for dark reactions, which produced glucose from carbon dioxide.
