The chloroplast is the organelle in a plant cell that captures the energy from the sun and converts it to chemical energy (glucose.) 2. 1) outer membrane 2) inner membrane 3) thylakoid 4) grana 5) stroma 3. The thylakoid is the structural unit of photosynthesis. The light dependent reacMons occur in photosystems that are embedded along the thylakoid membrane. A granum is a stack of thylakoids inside a chloroplast. The stroma is the soluMon that surrounds the thylakoids in a chloroplast. It contains enzymes, DNA, ribosomes, and other materials essenMal for photosynthesis. Copyright © Science Stuff
