For 10 points, name this organelle responsible for photosynthesis.
Precursor proteins are imported to this organelle using Tic and Toc proteins. Like mitochondria, these organelles are thought to have evolved through endosymbiosis (EN-do-sim-by-OH-sis). Lamella connect the grana inside this organelle. Those grana are stacks of suborganelles inside of which photophosphorylation (FO-toe-FOSS-for-ill-AY-shun) occurs. These organelles contain thylakoids, which possess light-absorbing pigments like chlorophyll. For 10 points, name this organelle responsible for photosynthesis.
