They are the sites of reactions that convert chemical energy from food molecules to ATP.
They have membranous sacs called thylakoids that are surrounded by a fluid called stroma.
Their inner membrane has infoldings called cristae.
They contain the green pigment chlorophyll.
Their matrix contains enzymes that function in cellular respiration.
They are the sites of reactions that convert solar energy into chemical energy.

Answer 1

The statements that are true for chloroplasts are:

1. They have membranous sacs called thylakoids that are surrounded by a fluid called stroma.
2. They contain the green pigment chlorophyll.
3. They are the sites of reactions that convert solar energy into chemical energy.
