WebJan 11, 2011 · The modeled chloroplast volume included three grana stacks of different sizes (yellow), and associated stroma thylakoids (green). However, to better illustrate the different types of stroma thylakoid configurations and grana-stroma thylakoid interactions, we have omitted several of the stroma thylakoids from the model (Fig. 2, D and E). Webchloroplasts. An organelle found in plants and photosynthetic protists. Enclosed by two concentric membranes, a chloroplast absorbs sunlight and uses it to power the synthesis of organic food molecules (sugars) chlorophyll. A light-absorbing pigment in chloroplasts that plays a central role in converting solar energy to chemical energy.
