Chloroplasts are the sites for photosynthesis and are found almost exclusively in plant cells. Clicking on each of the thumbnail
images will bring up a larger, labeled version of the described

In plant cells, another organelle called the chloroplast can convert light energy from the sun into chemical energy in the form of ATP through the process of photosynthesis.
Much like the electron transport system, photosyntheis involves electrons being transported between membrane bound complexes. This maintains a proton gradient that powers a similar ATP synthase complex and powers the production of ATP.
In photosynthesis, capturing the vibrational energy of light also powers the creation of molecular oxygen from the splitting of water molecules. This occurs in the oxygen evolving center of a complex called Photosystem II.
And that concludes our tour of the major organelles and processes found within our virtual cell. We are always working to add additional visualizations, so we encourage you to come back take advantage of our newest additions!
