For 10 points, name these double membrane bound organelles that are responsible for photosynthesis.
This structure is the site of most synthesis of a class of oxylipins containing characteristic cyclopentanone rings. The genomic region coding for this structure contain a core matK gene nested inside a trnK intron. Most jasmonate synthesis occurs in this structure, which contains a complex divided along a pseudosymmetric axis. A strong interacting dimer called "the special pair" is found in this structure, which contains (*) LH1 and LH2 complexes. One complex containing calcium and manganese, sometimes called the OEC, is found in one structure within this organelle. That complex is responsible for the oxidation of water. A pigment containing a central magnesium atom present in these organelles found in thylakoids, which are organized into stacks called grana. For 10 points, name these double membrane bound organelles that are responsible for photosynthesis.
