Saclike photosynthetic membranes that are interconnected and arranged into stacks are called?

Explanation:
In chloroplasts, the photosynthetic membranes are thylakoids, which are flattened sacs. When these thylakoids are interconnected and stacked like coins, each stack is called a granum. Several granum connected by stroma lamellae form the grana, increasing surface area for the light-dependent reactions. So the described saclike, interconnected, stacked membranes are grana. Lamellae are the connecting pieces between granum, vesicles are small sacs, and cristae are folds of the mitochondrial inner membrane.
