What are grana, thylakoids, and lamellae?
Grana are stacks of flattened sacs called thylakoids. Some thylakoids are joined by membranous extensions called lamellae.
The thylakoid membranes contain complexes of pigments that absorb light for photosynthesis. The light-dependent stage of photosynthesis takes place in the thylakoids.
