Question

Quizplus · Accepted Answer

Flattened sacs of internal membranes associated with photosynthesis are called thylakoids. Chloroplasts contain thylakoids along with other structures involved in photosynthesis. Photosystems are groups of pigments and proteins that convert light energy into chemical energy. The stroma is the fluid-filled space inside the chloroplast, surrounding the thylakoids. Cristae are the folded inner membranes of mitochondria.
