What is the structure and role of a chloroplast?

The chloroplast has a cell membrane like most cells/organelles. They are long and oval shaped with a similar shape/size to bacteria. Inside the organelle, the grana stack up like disks on top of one another. The thylakoid membrane that connects these grana contains chlorophyll, a green pigment that absorbs the energy of the sunlight (light dependent reaction). This energy is eventually converted into glucose in the stroma (light independent reaction). The thylakoid have a large surface area to absorb the maximum amount of sunlight possible. This increases the amount of glucose that can be made.
