Chloroplasts
absorbs sunlight and uses it to drive the synthesis of organic
compounds from carbon dioxide and water.
A flattened membrane sac inside the chloroplast, used to convert light
energy to chemical energy.
Thylakoids
Stomata
pores on the leaf where O2 exits and CO2 enters
The fluid of the chloroplast surrounding the thylakoid membrane;
Stroma
involved in the synthesis of organic molecules from carbon dioxide and
water.
A flattened, membranous sac inside a chloroplast. Thylakoids often exist
Thylakoids
in stacks called grana that are interconnected; their membranes contain
